SN74LVC2G74DCTR from Texas Instruments, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1CLR | input | Asynchronous clear, active-low. Driving low forces Q low and Q̄ high independent of CLK/D. CMOS input; VIH/VIL per LVC family levels. |
| 2 | 1D | input | Synchronous data input. Value is latched to Q on the rising edge of CLK when PRE and CLR are both high. |
| 3 | 1CLK | input | Clock input. Positive-edge triggered; D is transferred to Q on the low-to-high transition. |
| 4 | VCC | power_in | Positive supply, 1.65 V to 5.5 V (LVC family). Bypass with a 0.1 µF ceramic capacitor placed close to the pin. |
| 5 | 1PRE | input | Asynchronous preset, active-low. Driving low forces Q high and Q̄ low independent of CLK/D. When both PRE and CLR are low, both outputs are high (invalid state). |
| 6 | 1Q | output | Non-inverted flip-flop output. Push-pull CMOS drive; IOL/IOH per LVC datasheet (typically ±24 mA at 3.3 V). |
| 7 | 1Q_N | output | Inverted flip-flop output (Q̄), complementary to 1Q. Push-pull CMOS drive matched to 1Q. |
| 8 | GND | power_in | Ground reference (0 V) for the device. |
