What is Counter IC?
This is an integrated circuit that is built to count the input consisting of predefined clock pulses. The pulses can signal the time remaining for an event to occur or the intervals in time. This type of circuitry can read the counter data through the IC-bus interface.
The ability to read the counters enables the IC to support the production of many measuring instruments. It also helps in the production of infrastructure meters, amusement devices, and life counters, among others.
What are the Advantages of using counter ICs?
There are many advantages of using counter ICs. The following are some of them.
- When you construct your board using these ICs, you take less time to produce the final output. This is because you require fewer materials to build it.
- The overall mother-board space requirements when constructing these ICs are relatively small. This leaves you with more space for any additional components.
- This construction method will also save on costs as you require fewer components to get the task done.
- Counter ICs require less power to operate, which reduces a system’s overall power requirements. This also contributes to its cost-effectiveness.
- Synchronous countersare easy to design since you can set the same pulses for all logic gates. Asynchronous counter ICs can also be easily produced through the D-type flip flops or toggle.
- Some of the counters, like Synchronous counters, offer reliability since they are less prone to counting errors.
- Their operations are much quicker due to their low rate of propagation delays.
- They have state correction mechanisms, and this is helping in reducing the chance of crashes.
- You can implement counter integrated circuits using divide by n counter circuit.
- Because Counter ICs are truncated counters, they usually produce any modulus number count.
What are the Limitations of using Counter IC?
There are many shortcomings of using counter IC. These demerits are as follows.
Counter integrated circuit
- Some of them, like the asynchronous ones, may require re-synchronizing output flip flop.
- Counting a truncated sequence that is not equal to power 2, you must have extra feedback logic.
- Successive stages may cause propagation delay which may become too large when dealing with many number of bits. Therefore, their operations are much slower due to their high rate of propagation delays.
- Counter ICs, especially for Asynchronous, may develop counting errors when the counting frequencies are too high.
- For ripple counter, IC, all the bits of a count reach at different times, unlike the synchronous ones.
- Asynchronous counters are challenging to design. This is because you can have to set the flip flops to accept different pulses for your logic gates.
- Asynchronous counters do not have state correction mechanisms, which increase the chance of crashes.
- Their performance is dependent due to the circuitry required to create them.
How does Counter IC Work?
We have two main types of counters, that is, ripple and synchronous counters. These counter ICs work in relatively different ways.
Ripple counter has a chain of cascaded flip flops and a stage overflowing which causes a change in the subsequent stage. It is slow because of the few combined propagation rate of the flip-flops.
The synchronous one needs more combinations of flip-flop logic. All the flip-flops are clocked simultaneously. The D-input is the combinatorial logic output that aids in generating the next state considering the present state.
The entire counter chain of synchronous can be updated in one cycle propagation delay. Therefore, the synchronous counter IC is the fastest counter type.
What are the Types of Counter ICs?
There are many types of counter ICs. These include:
Synchronous: This is a counter IC that has a clock output across all its flip flop. It uses the same source to create the same clock signal simultaneously.
The external even will produce pulses that synchronize with the internal clock. A good example is ripple counter.
Synchronous counter IC
Asynchronous: These are counter ICs that have outputs that are free from the clock signals. They are supplied with a different clock signal, which results in delayed output production.
Asynchronous counter IC
The number of logic gates needed to design this counter IC is less than that required in the synchronous counter IC.
For this reason, they are simple in design. When a flip flop occurs, and the external event can be used to directly set or clear it.
Decade counter: It is a unique counter integrated circuit that can count up to 1010, which is basically decimal 10.
Basically, this is a binary counter.
You can achieve this using NAND Gate mainly to right of the schematic. It therefore implies that the inputs for the NAND Gate will be FF4 and FF2.
Ring counter: With these counters, a shift register is connected to the flip flops. You can achieve this using the last flip flop’s output.
You can feed it to the input of the first. Basically, this will result into a circular structure.
Ring counters used are ideal for counting data in a continuous loop.
AND & OR logic gates to the ring counter can be connected. This will help you to detect many pattern values in an information set.
5-bit ring counter can be produced by connecting three flip flops to form a state machine. In this case, five states or more states may be required to come up with this.
Cascade counter: This is a counter that has multiple connections which are connected one after the other. This is done to increase the modulus of the count sequence and frequency division.
Many stages of this type of counter are used in large applications. For example, digital time clocks, frequency divides, and synchronization of circuits.
Johnson counter: It is one of the synchronous counters. It’s a modified ring counter where the last flip-flop output is inverted. It is then fed back to the first as an input.
Sometimes, it is called inverse feedback or twisted ring counter. It enables connection of the last shift’s complement register to its input.
Normally, it will circulate stream of one and this can be followed by zero around the ring.
This counter may work as synchronous decade counter or divider circuit. Also, the integrated circuit counter is ideal for dividing the frequency of a clock signal y varying their feedback.
Modulus counter: You can refer to it as dividing number for integrated circuit counter. Also, it refers to the different states it counts in a given time.
You can always define these counter IC based on the states it goes through before returning to the original state or value.
What is the Counter IC used for?
The following are some of the uses of counter ICs.
They are used in making alarm clocks, setting air conditioner timer systems, and synchronizing light indicators in the automotive.
Counter ICs are also used to set the delay time in digital cameras. They are also used to control a scheduler’s ability to time a process.
Also, they are used as clock divider circuits, controlling the movement of machines and create staircase voltage.
Apart from these, Counter ICs’ parallel load feature can be used to present the counter for some initial count.
In addition to these, it can be used to produce keyboard controllers, microwaves, machines for washing, and digital clocks.
Lastly, Counter IC is used in digital-to-analog converters.
How is the Counter IC Assembled?
The assembly process of counter IC involves:
Assembly of counter IC
- Displaying circuits
Basically, you will need breadboard and 7-segment LED display.
Additionally, you will need:
- 4511 driver IC installed
- Different colors of hook-up wire
- 4029 CMOS counter IC
- ¼-watt resistor
First, you will begin by installing 4029 counter IC just on the right side of the 4511 decoder. Install IC and the necessary jumpers.
Now fix every component and test if the work effectively.
What Parameters are used in Classifying Counter ICs?
ICs have an interconnected internal chip, discrete devices and their corresponding connecting terminals positioned outside.
All the pins have their independent functions, and this may be different according to the design.
A fully operative pin is possible if the IC is used in supplying the voltage, input, and output connections.
It will also be operative when it is supplying voltage to some external components according to the producer requirements. Counter ICs can be classified as follows:
- 3-30 gates is small scale integration
- 30-300 gates is medium scale integration
- 300-3,000 gates is large scale integration
- Over 3,000 gates is very large scale integration
What is the difference between MOD-4 and MOD-8 counter?
MOD-4 is formed when two separate single flip-flops are combined to produce two different outputs.
The single outputs each results in a count of two, either a 0 or 1 on the clock signal application.
When these two flip-flops are put together, you get MOD-4.
Consequently, it will count in discrete steps which is always 4 in most cases.
Therefore, original clock input can now be divided by four.
Therefore, the 2-bit MOD-4 will have a binary sequence of:
On the contrary, a MOD-8 is formed by four separate single flip-flops that form four different outputs.
The integer values are increased on the clock, and it wraps round to 0 because the previous value was 7.
Therefore, the stored value will follow a cycle of 000, 001, 010, 011, 100, 101, 110, and 111.
In MOD-8, there are eight different states for counters, that is, one for each value from 0-7.
What is the difference between Asynchronous or ripple counters?
Asynchronous and ripple counter are the same.
In ripple counters, triggering of first flip-flop is due to the external clock. It is a type of asynchronous counter.
Furthermore, the preceding flip-flop output clocks the other flip-flop.
For frequency applications, you can choose 4-bit counter with MOD-16. It is a popular asynchronous counter.
Depending on the input, it can count:
- Down – 1111, 0010, etc.
- Up such as 0000, 0001, etc.
- Up and down
Normally, it repeats the count sequence.
When the un-complemented output is counted up, they complemented one will count down.
What is a 74LS193 Four-Bit Binary Counter?
It is a synchronous positive binary counter with 4-bit. Normally, it is edge triggered and can count either down or up.
It is a counter that has synchronous input for both pre-setting and clearing of the counter.
It has a programmable counter which facilitates the down and up counting. This also helps in controlling the count modulus via the use of asynchronous inputs. This type of counter has two individual clock inputs that ensure perfect control of up and down counting.
The maximum MOD-16 for this counter can be shortened to any modulus that is less than 16.
You can use asynchronous control input where you can reset the count stages back to zero.
You can preset the input counter stages a binary number, which is normally 4-bit. Normally, you can load this into an input which is parallel.
The counter can easily cascade as it counts up and down through the carry output and borrows output. This will help in lengthening the modulus and provide additional counter output stages.
What is a 74LS90 Decade Counter?
This is a high-speed ripple counter with 4-bits and it is divided into two parts. The counters are then divided by five, six, and eight forming LS90, LS92, and LS93, respectively.
A high to low transition triggers these counter division which are on the input of the clocks.
You can use each section independently. Alternatively, you can join them to make:
- Modulo-16 counters
All the counters have a two input gated master reset except LS90, which has a 2-input gated master set.
74LS90 consumes less power of about 45 Mw, and it has a high count rate of 42 MHZ.
How can one select an Integrated Circuit Counter?
There are many parameters you should be considered when selecting an integrated circuit chip. This can be done by matching the application requirements with counter capabilities.
Some of the main parameters to consider include:
- Counter modulus
- Counter modulus
- Output count
- Clock frequency
- Clock pulse
- Cascade input
Are Flip Flops Synchronous?
Yes, they are.
The input data to flip flops are called synchronous inputs. This is because they have some effect on the output in the step or sync with the clock signal transitions.
Why is Flip Flop called Latch?
They are called latches because they don’t have a clock. When changes are made at the input, it quickly latches to the required output directly without waiting for any signal.
How many Pins do IC 4017 have?
IC 4017 has 16 pins. These help in saving a lot of broad space and the time required to build a counter and a decoder IC.
The 16 pins of IC 4017 also helps in simplifying the design and makes debugging easy. Each pin has its separate function; for example, pin 1 is the output 5.
16 PIN Counter IC
How do IC 4017 help in saving Board Space?
The IC 4017 helps in saving board space because it’s used for producing low range applications. It can conduct a decade count from 0 to 10.
The circuits designed through IC 4017 does not only save board space but also saves on the design time.
What are the Components of Counter IC?
The components include many J-K flip flops connected in cascade and two up-counters, which:
- Mode-2 up counter
- MOD-8 up counter
How can you Test Counter IC?
To test the counter IC, you have to use two of 7476 ICs and one 7408 IC. The counter is tested to determine its proper sequence. The test is done to see if the counter can self-start.
The test involves initializing the counter to each of the unused states employing the pre-set and clear inputs.
The pulse transfers the counter to the valid state if at all, the counter is self-starting. If it’s not self-starting, then it means the pulse was not able to transfer the counter to the valid state.
What are the Quality Standards of Counter IC?
Counter IC, like any other device, should be made according to some acceptable standard. This is when it can be durable, safe, and function efficiently.
The following are some of these quality standards:
There has to be a quality assurance system in place that will guarantee the right quality for customers: The system should allow for regular design review so that the best quality can be presented to the market.
This is done by establishing a close relationship with the IC section to facilitate quick response to quality problems and complaints.
There should be a quality assurance at the counter IC development stage: The counter IC should be designed through the current market-oriented plan using reliable tools.
You have to begin by reviewing the basic functions. The engineering committee will look at the technology and update it appropriately.
Before you begin the process of manufacturing counter IC, it is important that you understand the process flow.
Finally, the product must be inspected to ensure it’s of the best quality that can compete in the market.
The quality of the counter IC is inspected to determine its characteristics and reliability. This is done during the development stage, at the trial of production, and before the mass production begins.
The reliability test should conform to:
- Or, any other test that strictly analyzes and establishes the required performance
At the counter IC development stage, the mass production test should be conducted if the device is intended for that.
At this stage, the quality assurance here will be that there is no problem with the device.
Raw and sub-raw materials quality assurance: The counter IC raw materials must be purchased from trusted and reliable producers.
After purchase, they must pass certain quality tests and requirements.
Any deviation from the purchase routes, type, or grade of counter IC material will lead to the second quality test. It makes it easier to maintain quality at all times.
The quality assurance before shipping the counter ICs: Counter IC should pass certain quality standards – from electrical, visual to performance characteristics.
Only those that pass quality tests move to the next stage in the production line.
Counter IC must be reliable: This is ascertained by carrying out a reliability test. Many reliability tests are meant for different purposes such as:
- Production approval
- New device assessment
There could be regular reliability tests that are normally implemented during mass production of counter ICs.
This is to make sure the counter IC reliability is established at the stage of development.
What is a Binary Counter IC?
This is a counter IC made from J-K flip flop. The cell output is taken to clock the input of the next cell.
The binary number is equal to that of cycles of signal at the input. You can also call it ripple through the counter.
What is the difference between 8-bit and 16-bit Binary counter IC?
The major difference between 8-bit and 16-bit binary counter IC is in their timers.
A microcontroller with 8 bits can use 8-bits. Consequently, it creates a final range of 0x00 to 0Xff (0-255) in every cycle.
On the other hand, 16-bit microcontrollers use a data width of 16-bit. It, therefore, has a range of 0x0000 – 0Xffff (0-65535) for every cycle.
What are the features of Counter IC?
Counter IC has many features. These features are outlined below.
- It has a high speed 16 pin CMOS decade counter.
- 10 decoded output can be supported by a counter IC.
- The counter IC has a characteristic of wide supply voltage range from 3v to 15 v. This is typically +5v.
- It is compatible with TTL
- Its operating clock frequency is 5 Mhz
- Counter IC has a high-level output voltage of 4.5V at 5V VCC.
- Its current output is also high, and it is at 0.36Ma.
- The counter IC can be found in 16-pin PDIP, GDIP, and PDSO packages.
How do you use the 7493 Counter IC?
It is an up-counter that has been built using four JK flip flops. A single flip flop is formed when CP1 and Q0 are connected to form MOD-2 counter.
The MOD-8 is formed when CP0 is connected to three flip flops of Q1, Q2, and Q3.
The 7493 counter IC can combine MOD-2 and MOD-8.
Consequently, this forms MOD-16 counter.
What is a 4 Bit Binary Counter?
It is asynchronous counter using JK flip flops. It is a machine that cycles through its states for each cycle of a clock signal.
How does a 4-bit Binary Counter Work?
The 4-bit binary is state equipment that cycles through its states for a cycle of a clock signal.
It works by cycling through its states for each cycle of a clock signal.
Its flip flops are connected through J-K terminals, thus putting them in toggle mode.
What is a Modulo 10 Counter?
This is a counter that has modulus and has a truncated sequence of ten (1010). It can sometimes be called MOD-10 or decade counter.
How do 3-bit and 4-bit Binary Counters compare?
A 3-bit counter is common in most electronics and it uses flip-flops of D-type. You can use it to count from 000 to 111.
It basically implies that the counting is from decimal of 0 to 7.
In short, such circuit has X, Y, and Z. In this case, Z is the crucial bit.
On the other hand, a 4-bit counter is a digital counter circuit. It produces a binary countdown that begins from 1111 to 0000. The 4-bit binary uses four D-type flip-flops that are triggered by a positive edge.
The flip flop feeds its inverted output back into its data input at every stage.
Which is the faster, Synchronous, or Asynchronous Counter?
The synchronous counter operates faster than the asynchronous counter. This is because, in the synchronous counter, all the flip flops are started by the same clock simultaneously.
On the other hand, asynchronous is relatively slow. This is because at a given time, the same clock does not trigger all the flip flops.
Each one begins to cycles at its time.
How do Mode 8 and Mode 6 Counters compare?
Mode 8 is a MOD counter that has a modulus value that is an integral power of 2. This will, therefore, have 2, 4, 8, and 16, among others.
These are natural counts that have not been repeated.
This will lead to the production of the n-bit counter.
Of course, it depends on the flip flops in the IC.
It will also depend on how they are connected, and this will determine the modulus and type of counter.
However, sometimes you should have a modulus counter. In fact, you need one that can reset its counts to zero.
Normally, this can happen as the counter IC works. It is possible as the counting process continues under normal circumstances. Of course, it’s modulus may not be power 2.
For instance, Mode 6 counter can be useful here. This is because it is a counter that has a modulus of 3, 5, 6, or 10.
What is a Parallel Counter IC?
They are counter integrated circuits that you can clock together virtually at the same time using the same clock signal.
Normally, the state of the output signal will change at the same time due to a common clock pulse.
Also, you can refer to parallel counters as synchronous counter. It is because you will feed clocks and flip flop in parallel.
What is a Clock Signal in the Counter IC?
In the counter IC, a clock signal is a particular signal that oscillates between high and low states. It is mainly used as a metronome to help coordinate digital circuit actions. A clock signal is generated by a clock generator.
In summary, before you choose a counter IC, you need to know every aspect that affects its functionality.
All that has been discussed in this guide.
Still, if you have concerns that have not been captured here, you can talk to use now.
