SN74AUP1G32DBVR 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	Input A of the 2-input OR gate. CMOS logic input with hysteresis (Vhys ≈ 250 mV typ at 3.3 V); tolerates 0 V to 3.6 V regardless of VCC. Ci ≈ 1.5 pF typ. Must not be left floating - tie unused inputs to VCC or GND.
2	B	input	Input B of the 2-input OR gate. CMOS logic input with hysteresis; 3.6 V I/O tolerant for mixed-voltage operation. Ci ≈ 1.5 pF typ. Must not be left floating.
3	GND	power_in	Ground reference (0 V) for the device.
4	Y	output	OR-gate output, Y = A + B. Push-pull CMOS output; IOH/IOL up to ±4 mA at VCC = 3 V (typ). Supports Ioff (live-insertion / partial-power-down) with back-drive protection.
5	VCC	power_in	Positive supply, 0.8 V to 3.6 V recommended (absolute max 4.6 V). ICC ≤ 0.9 µA max. Bypass locally with a 0.1 µF ceramic to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74aup1g32dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74aup1g32dbvr-etched.step`	2.5 MB	You want the part with `SN74AUP1G32DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 622 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.
