MC74HC1G14DFT2G from onsemi, 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 internal connection. Leave floating or tie to a stable potential per board practice.
2	IN A	input	Schmitt-trigger inverter input. VT+ = 2.86 V typ and VT- = 1.35 V typ at VCC = 4.5 V, providing 0.67 V typical hysteresis for noise-immune slow/noisy edge conditioning.
3	GND	power_in	Ground return (0 V) for the device.
4	OUT Y	output	Inverted CMOS push-pull output. Drives IOH = IOL = 2.0 mA (VCC = 4.5 V) with balanced tPLH/tPHL; logic-high when input is below VT-, logic-low when input is above VT+.
5	VCC	power_in	Positive supply, recommended operating range 2.0 V to 6.0 V (absolute max 7.0 V). Quiescent ICC = 1.0 uA typ at TA = 25 C.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc74hc1g14dft2g.step`	87 KB	You want the bare part, or you mark your own boards.
`mc74hc1g14dft2g-etched.step`	2.2 MB	You want the part with `MC74HC1G14DFT2G` 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.
