SN74LVC2G74DCUR from Texas Instruments, in a VSSOP-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 | CLK | input | Clock input. Data at D is transferred to Q on the positive-going edge of CLK when PRE and CLR are inactive (high). Accepts input voltages up to 5.5 V regardless of VCC. |
| 2 | D | input | Data input. Sampled on the rising edge of CLK and transferred to Q when PRE and CLR are inactive high. Input tolerant to 5.5 V. |
| 3 | ~{Q} | output | Complementary (inverted) flip-flop output. Drives ±24 mA at VCC = 3.3 V. Goes high when the internal Q latch is reset by CLR = L. |
| 4 | GND | power_in | Ground reference (0 V) for the device. |
| 5 | Q | output | True flip-flop output. Reflects the state of the D input following the rising edge of CLK. Drives ±24 mA at VCC = 3.3 V. |
| 6 | ~{CLR} | input | Active-low asynchronous clear input. A low level forces Q low regardless of CLK or D. Must be held high for normal clocked operation. |
| 7 | ~{PRE} | input | Active-low asynchronous preset input. A low level forces Q high regardless of CLK or D. Must be held high for normal clocked operation. |
| 8 | VCC | power_in | Positive supply voltage. Operating range 1.65 V to 5.5 V; data retention down to 1.5 V. Bypass locally with a 0.1 µF ceramic capacitor to GND. |
