What is 4026 IC in Digital Counters

Integrated Circuits play a vital role in the field of circuits and electronics. These are the combination of different fundamental devices in very specific yet functional ways. The 4026 belongs to the family of the Integrated Circuits in the series of 4000. The 4026 IC is introduced as:
"The 4026 is CMOS seven Segment counter  integrated Circuit that is the designed in decade Based and counts in the decimal digits and consist of total 16 pins." 
The output of the 4026 digital counter is usually fed into a 7 segment display Light Emitting Diode that shows the counter output of the 4026 IC Counter.Digital Counter, 4026 IC , Applications of 4026 IC, circuit of 4026 IC counter in Proteus, Proteus Projects.Being an IC, the pins of the 4026 Digital counter IC are very specific. By looking at the block diagram of 4026 IC Counter, we can generate a table that shows us the proper configuration of the 4026 IC.
Pin NumberPin NameDescription of the Pin
1Clock (CLK)With each positive clock Pulse, it increments the counter. 
2CI (Clock Inhibit)It is the Active high. When high, the counter freezes. When low, the clock pulse increments 7 segments.
3DE (Display Enable)Chip will ON when this is high and vise versa.
4DEO (Display Enable Out)Chaining 4026s.
5CO (Carry Out)It completes a single cycle after every 10 clock input cycles. It is used to change the clock manner of 1 counter into a multi counter.
6FThis Pin is connected to ‘f’ of the 7 segment.
7GThis pin is connected to ‘g’ of the 7 segment.
8VSSIt is the Ground PIN
9DIt is Connected to ‘d’ of the 7 segment.
10AIt connects with the  ‘a’ Pin of the 7 segment.
11EIt Connects the ‘e’ of the 7 segment with it.
12BIt Connects to the  ‘b’ of the 7 segment.
13CIt is Connected to ‘c’ of the 7 segment.
14UCS ( Un-gated C-Segment)It is an output for the seven-segment's C input that is not affected by the input of  DE . When the count is 2, it is high. 
15RST (Reset) Reset the counter to 0 when HIGH. Hence it is Active High.
16VDDPower supply PIN
In out experiment, we'll set all these pins according to our requirements to get the desired output. but some of the points here are pending to discuss. You may noticed the functioning of 6, 7, 9 to 13 pins of 4026 IC Counter. Let's have a look what does we mean by the description.

Seven Segment Display with 4026 IC Counter

This is the electronic device that is used to show the output of the counters such as 4026 IC. We define the Seven Segment Display as:
"The Seven Segment Display is a collection of 8 Light Emitting Diodes in a rectangular fashion that is an output device used to display the outcomes of different counters." 
For the convenience of connections, each LED of the Seven Segment Display is named i alphabetically and hence each pin of Seven Segment Display is connected with pins of 4026 IC Counter. Digital Counter, Seven Segment Display,4026 IC , Applications of 4026 IC, circuit of 4026 IC counter in Proteus, Proteus Projects.

Working of 4026 IC Digital Counter

  1. The Simulation of the circuit starts with the pulse generation at the Clock Pulse. These Pulses enters the BC547 MOSFET that regulates the pulses.
  2. The LED Connected to the BC547 MOSFET blink and we get the idea about the speed of the Pulse Generation.
  3. The Pulse enters the 4026 IC Counter and the counter Passes these pulses to the seven segment Display device.
  4. Each pulse from the 4026 IC power ups the respected LED of the seven segment display in a specific manner that we always get the digit as a result.
  5. The power is then Grounded connected to the seven segment display terminal.
  6. The output can be reset to the initial state with the button. This button is connected to the reset terminal of 4026 IC.

DID YOU KNOW ???

"You may skip the part of MOSFET and LED in the circuit but in some cases, when the error of the pulse occure, it may be difficult to examine whether the Pulses speed is low or there is another issue with the circuit."

  1. When the Frequency of the Clock Pulse is 1. The Digital counter 4026 IC shows us the value from zero to one in normal speed.
  2. Clicking the button resets the 4026 IC Digital Counter to the initial value, i.e, zero and starts the cycle.
  3. Changing the value of clock pulse to 10 will increase the digits changing the speed of the seven segment Display output.
  4. In two digits 4024 IC Counter, we can count the values till 99.
