74AHCT1G14SE-7 from Diodes Incorporated, in a SOT-353. 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 connection. Pin is not internally bonded; leave floating or tie to a stable potential per board practice.
2	A	input	Schmitt-trigger data input. Positive-going threshold VT+ typ 2.1V max at VCC=5.5V; negative-going threshold VT- typ 0.6V min at VCC=5.5V; hysteresis 0.4V to 1.6V. TTL-compatible input levels; tolerates slow input rise/fall (up to 20 ns/V).
3	GND	power_in	Ground reference (0 V). Continuous current through GND rated up to -50 mA.
4	Y	output	Push-pull data output; logic inverse of input A (Y = /A). Rated ±8 mA drive at VCC=5.0V; VOH ≥ 3.94V typ at IOH = -8 mA, VOL ≤ 0.36V typ at IOL = 8 mA (VCC = 4.5V).
5	VCC	power_in	Positive supply voltage. Operating range 4.5V to 5.5V; absolute maximum -0.5V to 6.5V. Typical quiescent supply current ICC = 2 μA (max 40 μA over full temperature).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74ahct1g14se-7.step`	87 KB	You want the bare part, or you mark your own boards.
`74ahct1g14se-7-etched.step`	1.9 MB	You want the part with `74AHCT1G14SE-7` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 495 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.
