SN74LVC1G00DBVR from UMW, 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	NAND gate input A. CMOS logic input, VIH ≥ 0.7·VCC and VIL ≤ 0.3·VCC at VCC = 3-5.5 V. Input leakage current typ. 0.1 µA (max ±5 µA) over 0-5.5 V range.
2	B	input	NAND gate input B. CMOS logic input, same thresholds and leakage as input A.
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 high drive: IOL/IOH up to ±32 mA at VCC = 4.5 V, ±16 mA at 3 V, ±8 mA at 2.3 V, ±4 mA at 1.65 V. VOH ≥ VCC − 0.1 V and VOL ≤ 0.1 V at 100 µA load.
5	VCC	power_in	Positive supply voltage, 1.65 V to 5.5 V operating (6.5 V absolute max). Quiescent current ICC typ. 0.1 µA, max 10 µA. Recommend a 0.1 µF decoupling capacitor to GND close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc1g00dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74lvc1g00dbvr-etched.step`	2.3 MB	You want the part with `SN74LVC1G00DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 588 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.
