SN74AHC1G04DBVR 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 connected to any internal die node.
2	A	input	Logic input to the inverter. CMOS/Schmitt-trigger input; recommended input voltage range 0 V to 5.5 V. Input leakage ±1 µA max; input capacitance ~2 pF typ.
3	GND	power_in	Ground reference (0 V) for the device. Connect to the system ground plane.
4	Y	output	Inverter output, Y = NOT A. Push-pull CMOS output rated ±8 mA at VCC = 5 V (±4 mA at 3.3 V); output swings rail-to-rail between GND and VCC.
5	VCC	power_in	Positive supply voltage input. Recommended operating range 2 V to 5.5 V; absolute max 7 V. Supply current ICC ≤ 10 µA max (static). Bypass locally with a 0.1 µF capacitor to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74ahc1g04dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74ahc1g04dbvr-etched.step`	2.3 MB	You want the part with `SN74AHC1G04DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 586 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.
