SN74LVC1G02DBVR 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	NOR gate logic input A. Standard CMOS input, high impedance, accepts voltages up to 5.5V regardless of VCC. Must not be left floating; terminate unused inputs to VCC or GND.
2	B	input	NOR gate logic input B. Standard CMOS input, high impedance, accepts voltages up to 5.5V regardless of VCC. Must not be left floating; terminate unused inputs to VCC or GND.
3	GND	power_in	Ground reference (0V). Connect directly to system ground plane.
4	Y	output	NOR gate output, Y = NOT(A + B). Balanced CMOS push-pull, ±24mA drive at VCC=3.3V (up to ±32mA at 4.5V). Do not leave unused push-pull outputs connected; leave disconnected if unused.
5	VCC	power_in	Positive supply voltage. Operating range 1.65V to 5.5V (1.5V minimum for data retention). Decouple with a local bypass capacitor to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc1g02dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74lvc1g02dbvr-etched.step`	2.3 MB	You want the part with `SN74LVC1G02DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 578 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.
