There are 10 pins, in which 8 pins are used to refer a,b,c,d,e,f,g and h/dp, the two middle pins are common anode/cathode of all he LEDs. We can refer each line/segment 'a,b,c,d,e,f,g' and for dot character we will use 'h'. It consists 8 LEDs, each LED used to illuminate one segment/line of the unit and the 8thLED used to illuminate DOT in 7 segment display. Reset the counter to 0 when HIGH.Ībove table explains the function of each pin of IC CD4016 clearly. This output is high unless the count is 2, when it goes low. Ungated C-segment - an output for the seven-segment's C input which is not affected by the DE input. The CARRY-OUT (Cout) signal completes one cycle every ten CLOCK INPUT cycles and is used to clock the succeeding decade directly in a multi-decade counting chain Freezes the counter when HIGH, active HIGH.ĭisplay enable- chip will be ON when this pin is HIGH, and OFF if it is LOW. Below is the pin diagram and pin description of 4026 IC:Ĭlock in, Increment the counter with each Positive clock pulse (LOW to HIGH).Ĭlock inhibit - when low, clock pulses increment the seven-segment. Means more the clock pulse rate, faster the numbers change in 7 segment Display. It is used to display numbers on seven segment displays and it increment the number by one, when a clock pulse is applied to its PIN 1. It is a decade counter, counts in decimal digits (0-9).

It is a CMOS seven-segment counter IC and can be operated at very low power. To use the 7 segment with ease, there is a 7 segment driver IC which is IC CD4026, so we are building 7 segment counter circuit using 4026 IC.Ĥ026 IC is a 4000 series IC. Counters are needed in object/products counters, digital stopwatches, calculators, timers etc. Digital counters are needed everywhere in this digital world, and 7 segment display is one the best component to display the numbers.
