74LVC1G126W5-7 from Diodes Incorporated, in a SOT-25. 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	Output Enable, active HIGH. HIGH enables the buffer so Y follows A; LOW places Y in high-impedance (Z) state. VIH ≥ 2V at VCC = 3V; VIL ≤ 0.8V at VCC = 3V. Unused inputs must be tied to VCC or GND.
2	A	input	Data Input to the non-inverting buffer. CMOS input, 5.5V tolerant regardless of VCC. Direct interface with TTL levels.
3	GND	power_in	Ground reference (0V) for the device.
4	Y	tri_state	Data Output from the non-inverting buffer with 3-state capability. Drives ±24mA at VCC = 3V; enters Hi-Z when OE = LOW. IOZ ≤ 10 µA (85°C) leakage in Z state.
5	VCC	power_in	Supply voltage, 1.65V to 5.5V operating (1.5V to 15V for data retention only). Decouple with 0.1µF close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74lvc1g126w5-7.step`	85 KB	You want the bare part, or you mark your own boards.
`74lvc1g126w5-7-etched.step`	2.0 MB	You want the part with `74LVC1G126W5-7` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 504 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.
