NC7S14M5X from onsemi, 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 connect. Not internally bonded; leave floating or tie to a static level per board convention.
2	A	input	Schmitt trigger inverter input. Positive-going threshold VP typ 1.90 V and negative-going threshold VN typ 1.05 V at VCC = 3.0 V (hysteresis VH typ ~0.85 V). Must be held HIGH or LOW; unused inputs may not float.
3	GND	power_in	Ground reference (0 V). Return for VCC supply and output currents.
4	Y	output	Inverted CMOS output (Y = /A). Balanced drive: 2 mA IOL / -2 mA IOH at VCC = 4.5 V. Rail-to-rail swing referenced to VCC and GND.
5	VCC	power_in	Positive supply voltage, 2.0 V to 6.0 V recommended (absolute max 7.0 V). Bypass locally with a 0.1 µF ceramic to GND. Quiescent supply current ICC < 1 µA typical.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`nc7s14m5x.step`	85 KB	You want the bare part, or you mark your own boards.
`nc7s14m5x-etched.step`	1.5 MB	You want the part with `NC7S14M5X` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 382 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.
