SN74LVC14ADR from Texas Instruments, 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. VT+ ≈ 1.1-2.0 V and VT- ≈ 0.8-1.7 V at VCC = 3.6 V; tolerates up to 5.5 V regardless of VCC.
3	2A	input	Schmitt-trigger data input to inverter 2. Same electrical characteristics as 1A; 5.5-V tolerant input.
5	3A	input	Schmitt-trigger data input to inverter 3. Same electrical characteristics as 1A; 5.5-V tolerant input.
9	4A	input	Schmitt-trigger data input to inverter 4. Same electrical characteristics as 1A; 5.5-V tolerant input.
11	5A	input	Schmitt-trigger data input to inverter 5. Same electrical characteristics as 1A; 5.5-V tolerant input.
13	6A	input	Schmitt-trigger data input to inverter 6. Same electrical characteristics as 1A; 5.5-V tolerant input.
2	1Y	output	Inverted data output of inverter 1 (Y = /A). Push-pull CMOS output; drives ±24 mA at VCC = 3 V.
4	2Y	output	Inverted data output of inverter 2 (Y = /A). Same drive strength as 1Y.
6	3Y	output	Inverted data output of inverter 3 (Y = /A). Same drive strength as 1Y.
8	4Y	output	Inverted data output of inverter 4 (Y = /A). Same drive strength as 1Y.
10	5Y	output	Inverted data output of inverter 5 (Y = /A). Same drive strength as 1Y.
12	6Y	output	Inverted data output of inverter 6 (Y = /A). Same drive strength as 1Y.
7	GND	power_in	Device ground reference. Common return for all six inverters.
14	VCC	power_in	Positive supply. Operating range 1.65 V to 3.6 V (SN74LVC14A). Bypass with a 0.1 µF ceramic close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc14adr.step`	195 KB	You want the bare part, or you mark your own boards.
`sn74lvc14adr-etched.step`	2.2 MB	You want the part with `SN74LVC14ADR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 576 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.
