74AHCT1G08SE-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	A	input	Data input A to the AND gate. TTL-compatible logic input with Schmitt-trigger action; VIH min 2.0 V, VIL max 0.8 V over VCC 4.5-5.5 V.
2	B	input	Data input B to the AND gate. TTL-compatible logic input with Schmitt-trigger action; VIH min 2.0 V, VIL max 0.8 V over VCC 4.5-5.5 V.
3	GND	power_in	Ground reference. Continuous current through GND rated to -50 mA absolute maximum.
4	Y	output	Data output of the AND gate (Y = A · B). Standard totem-pole CMOS output rated ±8 mA at VCC = 5.0 V; VOH ≥ 3.94 V and VOL ≤ 0.36 V at 25 °C with 8 mA load.
5	VCC	power_in	Positive supply voltage input. Recommended operating range 4.5 V to 5.5 V; absolute maximum -0.5 V to 6.5 V. Continuous ICC rated to 50 mA absolute maximum.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74ahct1g08se-7.step`	87 KB	You want the bare part, or you mark your own boards.
`74ahct1g08se-7-etched.step`	2.2 MB	You want the part with `74AHCT1G08SE-7` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 562 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.
