SN74LVC74AQPWRG4Q1 from Texas Instruments, in a TSSOP-14. 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 | 1CLR | input | Channel 1 clear input (active low); pulling low resets Q output to low level. |
| 2 | 1D | input | Channel 1 data input; sampled at positive clock edge. |
| 3 | 1CLK | input | Channel 1 clock input; positive edge triggered. |
| 4 | 1PRE | input | Channel 1 preset input (active low); pulling low sets Q output to high level. |
| 5 | 1Q | output | Channel 1 data output. |
| 6 | 1Q̄ | output | Channel 1 inverted data output. |
| 7 | GND | power_in | Ground reference (0V). |
| 8 | 2Q̄ | output | Channel 2 inverted data output. |
| 9 | 2Q | output | Channel 2 data output. |
| 10 | 2PRE | input | Channel 2 preset input (active low); pulling low sets Q output to high level. |
| 11 | 2CLK | input | Channel 2 clock input; positive edge triggered. |
| 12 | 2D | input | Channel 2 data input; sampled at positive clock edge. |
| 13 | 2CLR | input | Channel 2 clear input (active low); pulling low resets Q output to low level. |
| 14 | VCC | power_in | Power supply voltage; 2V to 3.6V operating range. |
