CD4017 - Decade Counter IC
The CD4017 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! See a circuit example further down.
Pin Overview:
| Pin Name | Pin # | Type | Description |
|---|---|---|---|
| VDD | 16 | Power | Supply Voltage (+3 to +15V) |
| GND | 8 | Power | Ground (0V) |
| Q0-Q9 | 1-7 and 9-11 | Output | Qx is high when the counter is x |
| CO | 12 | Output | Carry Out. Goes high after ten clock pulses |
| CI | 13 | Input | Clock Inhibit. Ignores clock inputs |
| CLK | 14 | Input | Clock Input. Increases the counter with one |
| MR | 15 | Input | Resets the counter to 0 |
