The HEF4017BT is a 16-pin Decade Counter/Divider with 10 Decoded Outputs. It is commonly used in sequential logic circuits to count from 0 to 9. Here's a brief overview of its pin count and functions:
1. Pin 1 to Pin 7, and Pin 9 to Pin 11 (Q0 to Q9): These are the decoded outputs of the counter. Each pin goes high sequentially on each clock pulse.
2. Pin 8 (VSS/GND): Ground pin for power supply.
3. Pin 12 (CARRY OUT): Outputs a carry signal which can be connected to the clock input of another counter to enable cascading.
4. Pin 13 (CLOCK INHIBIT): When held high, it disables the clock input, preventing the counter from advancing.
5. Pin 14 (CLOCK): Receives the clock signal to advance the counter.
6. Pin 15 (RESET): Resets the counter to zero when held high.
7. Pin 16 (VDD/VCC): Supply voltage pin for positive power supply.
The HEF4017BT is used in applications like LED chasers, event counters, and other sequential logic applications.
