CD4017 – Decade Counter IC

The CD4017 IC is adecade counterthat counts to ten. It has 10 outputs that represent the numbers 0 to 9. The counter increases with one for every rising clock pulse. After the counter has reached 9, it starts again from 0 with the next clock pulse.

This is a great chip for making running LEDs! See a circuit example further down.
