74LVC2G74DC from Nexperia, in a VSSOP-8-0.5mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CP | input | Clock input, edge-triggered on the LOW-to-HIGH transition; data at D that meets set-up and hold time is stored on that edge. |
| 2 | D | input | Data input that must meet the set-up and hold time requirements around the LOW-to-HIGH clock transition. |
| 3 | Q̄ | output | Complement output of the flip-flop. |
| 4 | GND | power_in | Ground (0 V). |
| 5 | Q | output | True output of the flip-flop. |
| 6 | RD | input | Asynchronous reset-direct input, active LOW; it forces Q LOW and Q̄ HIGH independently of CP. |
| 7 | SD | input | Asynchronous set-direct input, active LOW; it forces Q HIGH and Q̄ LOW independently of CP. |
| 8 | VCC | power_in | Supply voltage; recommended range is 1.65 V to 5.5 V, with an absolute maximum of -0.5 V to +6.5 V. |
