SN74LVC1G02DCKR 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 NOR gate. CMOS input, accepts 0 to 5.5 V regardless of VCC (supports down-translation). VIH is 0.7×VCC and VIL is 0.3×VCC at VCC = 4.5-5.5 V.
2	B	input	Logic input B of the 2-input NOR gate. CMOS input, accepts 0 to 5.5 V regardless of VCC. Unused inputs must be tied to VCC or GND per TI's slow/floating CMOS input guidance.
3	GND	power_in	Ground reference (0 V) for the device. Continuous current through GND is limited to ±100 mA (absolute maximum).
4	Y	output	NOR gate output, Y = NOT(A OR B). Push-pull CMOS output rated ±24 mA at VCC = 3 V (up to ±32 mA at VCC = 4.5 V). Continuous output current limited to ±50 mA (absolute maximum).
5	VCC	power_in	Positive supply, 1.65 V to 5.5 V operating (1.5 V data-retention only). Typical ICC ≤ 10 µA at 5.5 V; bypass with a local decoupling capacitor near the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc1g02dckr.step`	87 KB	You want the bare part, or you mark your own boards.
`sn74lvc1g02dckr-etched.step`	2.5 MB	You want the part with `SN74LVC1G02DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 614 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.
