SN74AHC1G32DBVR 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. Schmitt-trigger CMOS input, high-impedance when VCC = 0 V; accepts input voltages up to 5.5 V independent of VCC (down-voltage translation).
2	B	input	Logic input B of the 2-input positive-OR gate. Schmitt-trigger CMOS input, high-impedance when VCC = 0 V; accepts input voltages up to 5.5 V.
3	GND	power_in	Ground reference (0 V) for the device. Connect to system ground.
4	Y	output	OR-gate output (Y = A + B). Push-pull CMOS output rated ±8 mA at VCC = 5 V (±4 mA at 3.3 V); driven high when either input A or B is high.
5	VCC	power_in	Positive supply voltage, 2 V to 5.5 V recommended (7 V absolute max). Decouple with a 0.1 µF ceramic capacitor to GND close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74ahc1g32dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74ahc1g32dbvr-etched.step`	2.4 MB	You want the part with `SN74AHC1G32DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 605 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.
