CD4017 Decade Counter IC (DIP)

The CD4017 Decade Counter IC is a widely used CMOS digital logic IC designed for counting, sequencing, and driving applications. It is a 5-stage Johnson decade counter with 10 decoded outputs (Q0 to Q9) and a carry-out (COUT) signal, making it ideal for applications where sequential output or counting is required.

Operating with clock pulses, the IC advances one output high at a time in sequence, while all other outputs remain low. This feature makes it extremely useful in projects such as LED chasers, light sequencers, frequency dividers, and event counters. With a clock inhibit and reset pin, the counter operation can be controlled effectively, providing flexibility in design.

The CD4017 works with a wide supply voltage range from 3V to 15V, making it suitable for both TTL and CMOS logic circuits. Packaged in a standard DIP form factor, it is easy to use with breadboards and prototyping boards, making it a popular choice for students, hobbyists, and professionals.
