Description

The CD4017 is a CMOS Decade counter IC. CD4017 is used for low range counting applications. It can count from 0 to 10 (the decade count). The circuit designed by using this ic will save board space and also the time required to design the circuit.

CD4017 Pinout:

Pin Number

Pin Name

Description

1 to 7 and 9,10,11

Output pins Q0 to Q9

These are the 10 output pins on which the counting occurs, they are not in order hence verify the pin diagram above

8

Vss or Ground

Connected to the Ground of the circuit

12

Carry Out (CO)

This pin goes high after the IC counts from 1 to 10. This is used as carrying while counting.

13

Clock Enable (EN)

This is an input which when made high will hold the count at the current state

14

Clock

The counting happens when this clock pulse goes high, this pin is normally connected to 555 Timer or other uC to produce a pulse

15

Resets

As the name suggests this pin resets the count back to 1

16

Vdd / Vcc

Connects to the supply voltage typically +5V

 

Applications

  • Used in an LED matrix, LED chaser, and other LED projects
  • Binary counter or Binary decoder
  • Can be used for divide by N counting
  • Remote metering, automotive, medical electronics
