SN74LVC08ADR 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 input A. CMOS logic input; VIH >= 2 V (VCC = 2.7-3.6 V), VIL <= 0.8 V. Tolerates up to 5.5 V regardless of VCC.
2	1B	input	Channel 1 input B. CMOS logic input, 5.5 V tolerant.
3	1Y	output	Channel 1 output: 1Y = 1A AND 1B. Push-pull CMOS output; IOH/IOL = -24/24 mA at VCC = 3 V.
4	2A	input	Channel 2 input A. CMOS logic input, 5.5 V tolerant.
5	2B	input	Channel 2 input B. CMOS logic input, 5.5 V tolerant.
6	2Y	output	Channel 2 output: 2Y = 2A AND 2B. Push-pull CMOS output; IOH/IOL = -24/24 mA at VCC = 3 V.
7	GND	power_in	Ground reference (0 V) for all four gates.
8	3Y	output	Channel 3 output: 3Y = 3A AND 3B. Push-pull CMOS output; IOH/IOL = -24/24 mA at VCC = 3 V.
9	3A	input	Channel 3 input A. CMOS logic input, 5.5 V tolerant.
10	3B	input	Channel 3 input B. CMOS logic input, 5.5 V tolerant.
11	4Y	output	Channel 4 output: 4Y = 4A AND 4B. Push-pull CMOS output; IOH/IOL = -24/24 mA at VCC = 3 V.
12	4A	input	Channel 4 input A. CMOS logic input, 5.5 V tolerant.
13	4B	input	Channel 4 input B. CMOS logic input, 5.5 V tolerant.
14	VCC	power_in	Positive supply, 1.65 V to 3.6 V (SN74LVC08A). Absolute max 6.5 V. Bypass with a 0.1 uF ceramic near 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
`sn74lvc08adr.step`	195 KB	You want the bare part, or you mark your own boards.
`sn74lvc08adr-etched.step`	2.6 MB	You want the part with `SN74LVC08ADR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 643 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.
