IC Decade Counter 4017

IC Decade Counter 4017 - CMOS 4000 series is a family of standard integrated circuits which implement a variety of logic functions using technology Complementary Metal-Oxide-Semiconductor, and is still used today. They were introduced by RCA as CD4000 COS / MOS in 1968, as a component with low power usage and a more flexible alternative to the 7400 series TTL logic chips.

While IC IC 4017 is a 16-pin CMOS decade counter CMOS 4000 series ICs. It takes input clock pulse at clock pin input and will make one of the ten pin output to "turn on / off" in sequence at each clock pulse changes.

Example of a simple circuit of ic 4017 is to create a series of "running LED" or LED running:
