SN74LVC1G17DBVR 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	NC	unconnected	No internal connection. Leave floating or tie to a static level; not electrically connected inside the package.
2	A	input	Schmitt-trigger buffer input. Accepts logic levels up to 5.5V regardless of VCC (down-voltage translation). Positive-going threshold VT+ ≈ 1.48-1.92 V at VCC=3 V; negative-going threshold VT− ≈ 0.89-1.2 V at VCC=3 V. Input leakage ±5 µA max.
3	GND	power_in	Ground reference (0 V). Connect to system ground.
4	Y	output	Non-inverting buffered CMOS output (Y = A). Drives ±24 mA at VCC=3 V (up to ±32 mA at 4.5 V). VOH ≥ VCC−0.1 V at IOH=−100 µA; VOL ≤ 0.1 V at IOL=100 µA.
5	VCC	power_in	Positive supply, 1.65 V to 5.5 V operating (1.5 V min for data retention). Decouple locally with a 0.1 µF ceramic capacitor to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc1g17dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74lvc1g17dbvr-etched.step`	2.0 MB	You want the part with `SN74LVC1G17DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 520 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.
