74LVC1G125GW from Nexperia, in a SOT-353. 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	OE	input	Active-LOW output enable input (OE with overbar). When LOW, the buffer drives Y with the state of A. When HIGH, the Y output is placed in the high-impedance (Z) state. Schmitt-trigger input; overvoltage tolerant to 5.5 V.
2	A	input	Non-inverting data input to the buffer. Schmitt-trigger input, overvoltage tolerant to 5.5 V regardless of VCC. Drives output Y when OE is asserted (LOW).
3	GND	power_in	Ground reference (0 V). All voltages are referenced to this pin.
4	Y	tri_state	3-state buffer data output. Drives HIGH/LOW to match A when OE is LOW; high-impedance (Z) when OE is HIGH. Guaranteed ±24 mA drive at VCC = 3.0 V.
5	VCC	power_in	Positive supply voltage. Recommended operating range 1.65 V to 5.5 V; absolute maximum 6.5 V. Decouple locally to GND.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74lvc1g125gw.step`	87 KB	You want the bare part, or you mark your own boards.
`74lvc1g125gw-etched.step`	1.9 MB	You want the part with `74LVC1G125GW` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 477 faces against 102 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.
