74HC14D 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 to inverter 1. Typical VT+ ~2.38 V, VT- ~1.4 V at VCC=4.5 V; hysteresis ~0.98 V.
2	1Y	output	Inverting data output for channel 1. CMOS push-pull, capable of ±5.2 mA at VCC=6.0 V while maintaining valid levels.
3	2A	input	Schmitt-trigger data input to inverter 2.
4	2Y	output	Inverting data output for channel 2.
5	3A	input	Schmitt-trigger data input to inverter 3.
6	3Y	output	Inverting data output for channel 3.
7	GND	power_in	Ground reference (0 V).
8	4Y	output	Inverting data output for channel 4.
9	4A	input	Schmitt-trigger data input to inverter 4.
10	5Y	output	Inverting data output for channel 5.
11	5A	input	Schmitt-trigger data input to inverter 5.
12	6Y	output	Inverting data output for channel 6.
13	6A	input	Schmitt-trigger data input to inverter 6.
14	VCC	power_in	Positive supply voltage. Operating range 2.0 V to 6.0 V (74HC14); absolute max +7 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
`74hc14d.step`	195 KB	You want the bare part, or you mark your own boards.
`74hc14d-etched.step`	1.5 MB	You want the part with `74HC14D` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 413 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.
