74LVC14AD from Nexperia, in a SOIC-14. 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	1A	input	Schmitt-trigger data input for inverter 1. 5 V tolerant (VI up to 5.5 V) with typical hysteresis VH ~0.3 V to 1.2 V depending on VCC.
2	1Y	output	Inverted CMOS push-pull data output for inverter 1. Drives up to ±24 mA at VCC = 3.0 V.
3	2A	input	Schmitt-trigger data input for inverter 2. 5 V tolerant (VI up to 5.5 V).
4	2Y	output	Inverted CMOS push-pull data output for inverter 2. Drives up to ±24 mA at VCC = 3.0 V.
5	3A	input	Schmitt-trigger data input for inverter 3. 5 V tolerant (VI up to 5.5 V).
6	3Y	output	Inverted CMOS push-pull data output for inverter 3.
7	GND	power_in	Ground reference (0 V).
8	4Y	output	Inverted CMOS push-pull data output for inverter 4.
9	4A	input	Schmitt-trigger data input for inverter 4. 5 V tolerant (VI up to 5.5 V).
10	5Y	output	Inverted CMOS push-pull data output for inverter 5.
11	5A	input	Schmitt-trigger data input for inverter 5. 5 V tolerant (VI up to 5.5 V).
12	6Y	output	Inverted CMOS push-pull data output for inverter 6.
13	6A	input	Schmitt-trigger data input for inverter 6. 5 V tolerant (VI up to 5.5 V).
14	VCC	power_in	Supply voltage. Recommended 1.65 V to 3.6 V (functional down to 1.2 V); absolute max 6.5 V. Decouple with 100 nF close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74lvc14ad.step`	195 KB	You want the bare part, or you mark your own boards.
`74lvc14ad-etched.step`	1.6 MB	You want the part with `74LVC14AD` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 444 faces against 237 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.
