SN74AHC1G00DBVR 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	A input of the 2-input NAND gate. CMOS logic input with Schmitt-trigger action. VIH ranges from 1.5 V (VCC = 2 V) to 3.85 V (VCC = 5.5 V).
2	B	input	B input of the 2-input NAND gate. CMOS logic input with Schmitt-trigger action. Unused inputs must be tied to VCC or GND.
3	GND	power_in	Ground reference (0 V) for the device.
4	Y	output	NAND gate output, Y = NOT(A AND B). Push-pull CMOS output with ±8 mA drive at VCC = 5 V (±4 mA at 3.3 V).
5	VCC	power_in	Positive supply voltage input. Operating range 2 V to 5.5 V. Absolute maximum 7 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
`sn74ahc1g00dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74ahc1g00dbvr-etched.step`	2.4 MB	You want the part with `SN74AHC1G00DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 609 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.
