CD4017 Pin Configuration

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 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 carry 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

Features

  • High speed 16 pin CMOS Decade counter
  • Supports 10 decoded outputs
  • Wide supply voltage range from 3V to 15V, typically +5V
  • TTL compatible
  • Maximum Clock Frequency: 5.5Mhz
  • Available in 16-pin PDIP, GDIP, PDSO packages

Applications

  • Alarm Systems
  • Remote Metering
  • Automotive
  • Medical Electronics
  • Running Lightings

Where to use CD4017 IC

The IC CD4017 is used for counting applications, it has the capability to turn on 10 outputs sequentially in a pre-defined time and reset the count or hold it when required. It also has the capability to indicate the status of counting using Carry pin. This is commonly used for Led chasers and other logical output projects, so if you are looking for an sequential decoded counting IC that can count up to 10 then this IC will be your right choice

 

How to use a CD4017 IC

The IC can work from 3V to 15V, but normally powered with +5V to the Vdd/Vcc pin and the Ground/Vss pin is connected to ground. We have 10 output pins ranging from Q0 to Q9, these pins can be connected to any load but we are using LEDs here as shown in the circuit below.

CD4017 Circuit Diagram

This IC will increment the count from 0 to 9 (Q0 to Q9) each time it senses a high pulse from the clock pin (pin 14). So we need a clock source to keep this IC ticking, this clock source can be a simple Timer circuit that could generate pulse or a microcontroller like ArduinoPIC etc to generate our custom pulse using I/O pins.

  • The supply voltage of this IC is 3V to 15V.
  • It is compatible with TTL (Transistor-Transistor Logic).
  • The clock speed or operational speed of CD4017 IC is 5 MHz
  • 5-stage Divide-by-10 Johnson Counter with 10 Decoded Outputs and a Carry Bit
  • Medium Speed up to 5MHz
  • Operating Temperature to 85°C.
