## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1Q | output | True output of flip-flop 1; latches data on positive clock edge |
| 2 | /1Q | output | Complement output of flip-flop 1; inverted state of 1Q |
| 3 | 1CP | input | Clock input for flip-flop 1; positive-going edge (LOW to HIGH) triggers data transfer |
| 4 | 1CD | input | Asynchronous clear-direct input for flip-flop 1; active HIGH, overrides clock and data inputs |
| 5 | 1D | input | Data input for flip-flop 1; sampled when clock input is LOW |
| 6 | 1SD | input | Asynchronous set-direct input for flip-flop 1; active HIGH, overrides clock and data inputs |
| 7 | VSS | power_in | Ground (0V); voltage reference for the device |
| 8 | 2SD | input | Asynchronous set-direct input for flip-flop 2; active HIGH, overrides clock and data inputs |
| 9 | 2D | input | Data input for flip-flop 2; sampled when clock input is LOW |
| 10 | 2CD | input | Asynchronous clear-direct input for flip-flop 2; active HIGH, overrides clock and data inputs |
| 11 | 2CP | input | Clock input for flip-flop 2; positive-going edge (LOW to HIGH) triggers data transfer |
| 12 | /2Q | output | Complement output of flip-flop 2; inverted state of 2Q |
| 13 | 2Q | output | True output of flip-flop 2; latches data on positive clock edge |
| 14 | VDD | power_in | Supply voltage; operating range 3V to 15V referenced to VSS |
