74LVC1G125SE-7 from Diodes Incorporated, 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. When LOW the buffer drives Y from A; when HIGH the output Y is placed in high-impedance (3-state). VIH/VIL scale with VCC (e.g. 0.7VCC / 0.3VCC at 4.5-5.5 V).
2	A	input	Data input to the non-inverting buffer. CMOS/TTL-compatible; tolerates up to 5.5 V regardless of VCC to support level-shifting applications.
3	GND	power_in	Ground (0 V) reference for the device.
4	Y	tri_state	Data output from the non-inverting buffer. Drives up to +/-24 mA at VCC = 3 V (up to +/-32 mA at 4.5 V). Enters high-impedance when OE is HIGH.
5	VCC	power_in	Positive supply voltage. Operating range 1.65 V to 5.5 V (1.5 V min for data retention). Absolute maximum 6.5 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74lvc1g125se-7.step`	87 KB	You want the bare part, or you mark your own boards.
`74lvc1g125se-7-etched.step`	2.0 MB	You want the part with `74LVC1G125SE-7` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 515 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.
