SN74LVC1G07DBVR 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 GND per board practice.
2	A	input	Buffer/driver logic input. Accepts 0 V to 5.5 V independent of VCC (1.65 V to 5.5 V). VIH/VIL scale with VCC (e.g., 2 V VIH at VCC = 3.0-3.6 V).
3	GND	power_in	Ground reference (0 V) for the device.
4	Y	output	Open-drain buffer output. Requires an external pull-up (to any rail up to 5.5 V, independent of VCC) for wired-OR / wired-AND / level-shifting. Sinks up to 32 mA (IOL = 32 mA at VCC = 4.5 V); ±24 mA drive at 3.3 V.
5	VCC	power_in	Positive supply, 1.65 V to 5.5 V (data retention only down to 1.5 V). Bypass to GND with a local decoupling capacitor.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc1g07dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74lvc1g07dbvr-etched.step`	2.1 MB	You want the part with `SN74LVC1G07DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 550 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.
