74AHC1GU04SE-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	NC	unconnected	No connection. Pin is not internally bonded; leave floating or tie to GND/VCC per board convention.
2	A	input	Data input to the unbuffered inverter. VIH is 1.7 V at VCC=2 V, 2.4 V at VCC=3 V, and 4.4 V at VCC=5.5 V. Unused inputs should be tied to VCC or GND.
3	GND	power_in	Ground reference (0 V). Continuous current through GND rated up to -50 mA (absolute maximum).
4	Y	output	Inverted data output (Y = /A) with a totem-pole (push-pull) driver. Drive capability ±6 mA at VCC=5 V, ±3 mA at VCC=3.3 V.
5	VCC	power_in	Positive supply voltage, 2.0 V to 5.5 V operating range (absolute max -0.5 V to 6.5 V). Bypass with a local 0.1 µF ceramic capacitor to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74ahc1gu04se-7.step`	87 KB	You want the bare part, or you mark your own boards.
`74ahc1gu04se-7-etched.step`	2.2 MB	You want the part with `74AHC1GU04SE-7` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 553 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.
