SN74AHCT1G08DBVR from Texas Instruments, in a SOT-23-5. 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	Logic input A of the 2-input AND gate. TTL-compatible; VIH ≥ 2 V, VIL ≤ 0.8 V over VCC = 4.5-5.5 V. Unused inputs must be tied to VCC or GND.
2	B	input	Logic input B of the 2-input AND gate. TTL-compatible; VIH ≥ 2 V, VIL ≤ 0.8 V over VCC = 4.5-5.5 V. Unused inputs must be tied to VCC or GND.
3	GND	power_in	Ground reference pin (0 V). Return for VCC supply and all logic signals.
4	Y	output	Push-pull AND-gate output (Y = A · B). Rated for ±8 mA drive at VCC = 5 V; VOH ≥ 3.94 V and VOL ≤ 0.36 V at 25°C.
5	VCC	power_in	Positive supply pin. Recommended operating range 4.5 V to 5.5 V; absolute maximum 7 V. Bypass locally with a 0.1 µF ceramic capacitor to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74ahct1g08dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74ahct1g08dbvr-etched.step`	2.5 MB	You want the part with `SN74AHCT1G08DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 637 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.
