SN74AHCT1G14DBVR 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 VCC/GND per board convention.
2	A	input	Data input to the Schmitt-trigger inverter. TTL-compatible input with hysteresis (typ VT+ ≈ 1.6 V, VT- ≈ 1.1 V at VCC = 5 V). Input voltage range 0 to 5.5 V; must not be left floating.
3	GND	power_in	Ground reference (0 V) for the device.
4	Y	output	Inverted data output (Y = A̅). Push-pull CMOS output rated ±8 mA at VCC = 5 V; VOH ≥ 3.94 V @ IOH = -8 mA, VOL ≤ 0.36 V @ IOL = 8 mA (VCC = 4.5 V).
5	VCC	power_in	Positive supply voltage. Recommended operating range 4.5 V to 5.5 V; absolute maximum 7 V. Decouple with a 100 nF ceramic capacitor to GND close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74ahct1g14dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74ahct1g14dbvr-etched.step`	2.2 MB	You want the part with `SN74AHCT1G14DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 570 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.
