Pinout
This device comes in a 14-pin package. Here is a concise description of the pin functions:
1. Pins 1 & 13: Preset (Set) for each flip-flop.
2. Pins 2 & 12: Clock input for each flip-flop.
3. Pins 3 & 11: Data input (D) for each flip-flop.
4. Pins 4 & 10: Complementary output (\(\overline{Q}\)) for each flip-flop.
5. Pins 5 & 9: True output (Q) for each flip-flop.
6. Pins 6 & 8: Clear (Reset) for each flip-flop.
7. Pin 7: Ground (GND).
8. Pin 14: Positive supply voltage (VCC).
The flip-flops are edge-triggered, meaning they change state on the rising edge of the clock signal. The preset and clear inputs are asynchronous, allowing the outputs to be set or reset regardless of the clock state.
