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.
