CD4017BD – Decade Counter
The CD4017BD IC is a decade counter that 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 for your props!
Typical applications for the CD4017BD include LED chasers, alarms, frequency dividers, or even a music sequencer.
