NC7SZ14M5X 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. Leave floating or tie to ground; not internally bonded.
2	A	input	Schmitt-trigger inverter input. 5.5 V tolerant regardless of VCC. Typical hysteresis 0.77 V at VCC = 3 V; positive threshold ~1.75 V and negative threshold ~1.00 V at VCC = 3 V. Must not float when unused (tie HIGH or LOW).
3	GND	power_in	Device ground reference (0 V).
4	Y	output	Inverting CMOS push-pull output (Y = /A). High output drive ±24 mA at VCC = 3 V (rated up to IOL/IOH = 32 mA at 4.5 V). Propagation delay tPD ~3.7 ns typical into 50 pF at 5 V VCC.
5	VCC	power_in	Positive supply voltage. Operating range 1.65 V to 5.5 V; data-retention range 1.5 V to 5.5 V. Quiescent ICC ≤ 1 µA typical.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`nc7sz14m5x.step`	85 KB	You want the bare part, or you mark your own boards.
`nc7sz14m5x-etched.step`	1.6 MB	You want the part with `NC7SZ14M5X` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 403 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.
