SN74AC04DR 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	Channel 1 inverter input A. CMOS logic input; VIH >= 3.15 V and VIL <= 1.35 V at VCC = 4.5 V. Do not leave floating.
2	1Y	output	Channel 1 inverter output Y = /1A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
3	2A	input	Channel 2 inverter input A. CMOS logic input; do not leave floating.
4	2Y	output	Channel 2 inverter output Y = /2A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
5	3A	input	Channel 3 inverter input A. CMOS logic input; do not leave floating.
6	3Y	output	Channel 3 inverter output Y = /3A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
7	GND	power_in	Device ground reference (0 V).
8	4Y	output	Channel 4 inverter output Y = /4A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
9	4A	input	Channel 4 inverter input A. CMOS logic input; do not leave floating.
10	5Y	output	Channel 5 inverter output Y = /5A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
11	5A	input	Channel 5 inverter input A. CMOS logic input; do not leave floating.
12	6Y	output	Channel 6 inverter output Y = /6A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
13	6A	input	Channel 6 inverter input A. CMOS logic input; do not leave floating.
14	VCC	power_in	Positive supply, 2 V to 6 V recommended (7 V absolute max). Bypass with a 0.1 uF ceramic capacitor to GND close to the pin.

CAD (KiCad official)

3D model: SOIC-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74ac04dr.step`	195 KB	You want the bare part, or you mark your own boards.
`sn74ac04dr-etched.step`	2.2 MB	You want the part with `SN74AC04DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 574 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.
