MC74HC14ADR2G from onsemi, 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	A1	input	Schmitt-trigger input of inverter 1. Compatible with standard CMOS output levels; input leakage typ 0.1 uA. Threshold hysteresis Vh typ 1.65 V @ Vcc=3.0 V.
2	Y1	output	Inverted output of gate 1 (Y = /A). CMOS push-pull output, drives up to 10 LSTTL loads; Iout max +/-25 mA per pin.
3	A2	input	Schmitt-trigger input of inverter 2.
4	Y2	output	Inverted output of gate 2 (Y = /A). CMOS push-pull output.
5	A3	input	Schmitt-trigger input of inverter 3.
6	Y3	output	Inverted output of gate 3 (Y = /A).
7	GND	power_in	Ground reference (0 V). Datasheet explicitly notes 'Pin 7 = GND'.
8	Y4	output	Inverted output of gate 4 (Y = /A).
9	A4	input	Schmitt-trigger input of inverter 4.
10	Y5	output	Inverted output of gate 5 (Y = /A).
11	A5	input	Schmitt-trigger input of inverter 5.
12	Y6	output	Inverted output of gate 6 (Y = /A).
13	A6	input	Schmitt-trigger input of inverter 6.
14	VCC	power_in	Positive supply voltage. Operating range 2.0 V to 6.0 V (absolute max 7.0 V). Datasheet notes 'Pin 14 = Vcc'. Bypass with 0.1 uF ceramic to GND close to pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc74hc14adr2g.step`	195 KB	You want the bare part, or you mark your own boards.
`mc74hc14adr2g-etched.step`	2.5 MB	You want the part with `MC74HC14ADR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 649 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.
