CD4017 CMOS Counter IC: Equivalent, Price and Datasheet

The CD4017 IC is a CMOS decade counter which consists of 10 Johnson counters with 10 decoded outputs and a carry-out bit. and it is used in the applications of low-range counting. This IC will count from 0 to 10 by turning on the 10 outputs one by one on every positive edge of a clock. And the circuit with an IC 4017 will save board space as well as the time necessary to design the circuit. We can reset and control counting with the help of reset and enable pins. This decade counter is similar to Johnson 10 stage decade counter. This CMOS IC is frequently used in designing the 10 LEDs-based circuits to run the light for beginners. So it is one of the most flexible counters because it counts up to 10 & also it includes 10 separate outputs. This IC includes the counter as well as the decoder.

The most popular IC like CD4017 is extensively used in different applications which include Decoder, Binary counter, Frequency division, Decade counter, etc. 

Additionally, this IC is also used to make different electronics projects like Remote controlled switches, light chasers, Touch ON-OFF switches, Alarm, Matrix Die, Clap switches, etc. 

This decade counter IC can also be used in different industries like automotive, alarms, electronic manufacturing of medical instruments & instrumentation devices.

CD4017 has 10 output pins range from Q0 to Q9, which are connected to any load however we are using LEDs in the circuit. that gets HIGH in a sequential pattern when the clock signal is applied. 

This clock signal can be generated through 555 timer IC or any other digital IC’s. Pin 13 which is a clock enable pin is kept LOW otherwise it can halt the clock signal. 

The Reset Pin is also kept LOW. This pin is responsible for resetting the counter to restart the counting from 0. Therefore, for the normal operation of a circuit, these two pins are kept LOW.

■Used in LED matrix circuit, LED chaser application, and other LED-based projects

■Used in Binary counter or Binary decoder

■Used in Divisiable counting by N

■Used in Remote metering, automotive,  industrial, medical electronics
