SN74LVC1G74DCUR 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 the D input is transferred to Q on the positive (rising) edge of CLK, provided setup/hold requirements are met. |
| 2 | D | input | Data input to the D-type flip-flop. Logic level present at D is captured to Q on the rising edge of CLK. |
| 3 | ~{Q} | output | Inverted (complementary) flip-flop output. Drives ±24 mA at VCC = 3.3 V. |
| 4 | GND | power_in | Ground reference (0 V) for the device. |
| 5 | Q | output | Non-inverted flip-flop output. Drives ±24 mA at VCC = 3.3 V. |
| 6 | ~{CLR} | input | Active-low asynchronous clear input. Pull low to force Q low (and ~{Q} high) regardless of CLK/D. Must be held high (inactive) for normal clocked operation. |
| 7 | ~{PRE} | input | Active-low asynchronous preset input. Pull low to force Q high (and ~{Q} low) regardless of CLK/D. Must be held high (inactive) for normal clocked operation. |
| 8 | VCC | power_in | Positive supply voltage, 1.65 V to 5.5 V operating range (1.5 V minimum for data retention only). |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 622 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
