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
