SN74HC08PWR from Texas Instruments, in a TSSOP-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 to gate 1. VIH >= 3.15 V at VCC = 4.5 V; VIL <= 1.35 V at VCC = 4.5 V. Unused inputs must be tied to VCC or GND.
2	1B	input	Channel 1, Input B. CMOS logic input to gate 1. Same electrical characteristics as input 1A.
3	1Y	output	Channel 1, Output Y. CMOS logic output; Y = 1A AND 1B. Drives up to ±4 mA at VCC = 4.5 V while maintaining valid CMOS levels.
4	2A	input	Channel 2, Input A. CMOS logic input to gate 2.
5	2B	input	Channel 2, Input B. CMOS logic input to gate 2.
6	2Y	output	Channel 2, Output Y. CMOS logic output; Y = 2A AND 2B.
7	GND	power_in	Ground return (0 V) for the device. Continuous current through VCC or GND must not exceed 50 mA.
8	3Y	output	Channel 3, Output Y. CMOS logic output; Y = 3A AND 3B.
9	3A	input	Channel 3, Input A. CMOS logic input to gate 3.
10	3B	input	Channel 3, Input B. CMOS logic input to gate 3.
11	4Y	output	Channel 4, Output Y. CMOS logic output; Y = 4A AND 4B.
12	4A	input	Channel 4, Input A. CMOS logic input to gate 4.
13	4B	input	Channel 4, Input B. CMOS logic input to gate 4.
14	VCC	power_in	Positive supply input. Recommended operating range 2 V to 6 V (nominal 5 V); absolute maximum 7 V. Bypass with a 0.1 µF ceramic capacitor to GND close to the pin.

CAD (KiCad official)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74hc08pwr.step`	194 KB	You want the bare part, or you mark your own boards.
`sn74hc08pwr-etched.step`	2.6 MB	You want the part with `SN74HC08PWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 645 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.
