SN74HCS74PWR 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 | 1CLR̄ | input | Asynchronous clear (active low) for flip-flop 1; resets Q output to low independent of clock and data inputs |
| 2 | 1D | input | Data input for flip-flop 1; sampled and transferred to Q outputs on rising clock edge when clear and preset are inactive |
| 3 | 1CLK | input | Clock input for flip-flop 1 with Schmitt-trigger; rising edge triggered with 7-15 ns typical propagation delay at 6V |
| 4 | 1PRĒ | input | Asynchronous preset (active low) for flip-flop 1; sets Q output high independent of clock and data inputs |
| 5 | 1Q | output | Q output for flip-flop 1; can drive 7.8 mA at 6V with balanced CMOS push-pull output |
| 6 | 1Q̄ | output | Inverted Q output for flip-flop 1; complements 1Q with 7.8 mA drive capability at 6V |
| 7 | GND | power_in | Ground; negative supply reference and logic return for the device |
| 8 | 2Q̄ | output | Inverted Q output for flip-flop 2; complements 2Q with 7.8 mA drive capability at 6V |
| 9 | 2Q | output | Q output for flip-flop 2; can drive 7.8 mA at 6V with balanced CMOS push-pull output |
| 10 | 2PRĒ | input | Asynchronous preset (active low) for flip-flop 2; sets Q output high independent of clock and data inputs |
| 11 | 2CLK | input | Clock input for flip-flop 2 with Schmitt-trigger; rising edge triggered with 7-15 ns typical propagation delay at 6V |
| 12 | 2D | input | Data input for flip-flop 2; sampled and transferred to Q outputs on rising clock edge when clear and preset are inactive |
| 13 | 2CLR̄ | input | Asynchronous clear (active low) for flip-flop 2; resets Q output to low independent of clock and data inputs |
| 14 | VCC | power_in | Positive supply voltage; 2V to 6V recommended operating range with 100 nA typical quiescent current |
