SN74LVC1G32DCKR from Texas Instruments, in a SC-70-5. 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 OR gate. Accepts CMOS logic levels up to 5.5 V regardless of VCC (enables voltage down-translation).
2	B	input	Logic input B of the 2-input OR gate. Accepts CMOS logic levels up to 5.5 V regardless of VCC.
3	GND	power_in	Device ground reference (0 V). Must be connected to system ground.
4	Y	output	OR-gate output, Y = A + B. Push-pull CMOS output rated ±24 mA drive at VCC = 3.3 V.
5	VCC	power_in	Positive supply pin. Recommended operating range 1.65 V to 5.5 V (Absolute Max 6.5 V). Bypass 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
`sn74lvc1g32dckr.step`	87 KB	You want the bare part, or you mark your own boards.
`sn74lvc1g32dckr-etched.step`	2.5 MB	You want the part with `SN74LVC1G32DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 620 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.
