SN74AHCT1G32DBVR 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 positive-OR gate. TTL-voltage compatible; VIH ≥ 2 V, VIL ≤ 0.8 V over VCC = 4.5-5.5 V. Must be driven or tied to VCC/GND (no floating inputs).
2	B	input	Logic input B of the 2-input positive-OR gate. TTL-voltage compatible; VIH ≥ 2 V, VIL ≤ 0.8 V over VCC = 4.5-5.5 V. Must be driven or tied to VCC/GND (no floating inputs).
3	GND	power_in	Device ground reference (0 V). Return path for VCC supply current (typ 1 µA, max 10 µA quiescent) and output sink current.
4	Y	output	Push-pull logic output. Y = A + B (positive-OR). Drives ±8 mA at VCC = 4.5 V (VOH ≥ 3.94 V at IOH = −8 mA; VOL ≤ 0.36 V at IOL = 8 mA).
5	VCC	power_in	Positive supply, 4.5 V to 5.5 V recommended (7 V absolute maximum). Bypass locally with a 0.1 µF ceramic capacitor to GND. Quiescent ICC = 10 µA max.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74ahct1g32dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74ahct1g32dbvr-etched.step`	2.4 MB	You want the part with `SN74AHCT1G32DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 619 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.
