SN74LVC00APWR 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	Gate 1 input A. CMOS logic input; VIH ≥ 2 V and VIL ≤ 0.8 V at VCC = 2.7-3.6 V. 5.5 V tolerant.
2	1B	input	Gate 1 input B. CMOS logic input; VIH ≥ 2 V and VIL ≤ 0.8 V at VCC = 2.7-3.6 V. 5.5 V tolerant.
3	1Y	output	Gate 1 output. Y = NOT(1A AND 1B). Push-pull CMOS output; IOH = -24 mA, IOL = 24 mA at VCC = 3 V.
4	2A	input	Gate 2 input A. CMOS logic input; 5.5 V tolerant.
5	2B	input	Gate 2 input B. CMOS logic input; 5.5 V tolerant.
6	2Y	output	Gate 2 output. Y = NOT(2A AND 2B). Push-pull CMOS output; ±24 mA drive at VCC = 3 V.
7	GND	power_in	Ground reference (0 V) for the device.
8	3Y	output	Gate 3 output. Y = NOT(3A AND 3B). Push-pull CMOS output; ±24 mA drive at VCC = 3 V.
9	3A	input	Gate 3 input A. CMOS logic input; 5.5 V tolerant.
10	3B	input	Gate 3 input B. CMOS logic input; 5.5 V tolerant.
11	4Y	output	Gate 4 output. Y = NOT(4A AND 4B). Push-pull CMOS output; ±24 mA drive at VCC = 3 V.
12	4A	input	Gate 4 input A. CMOS logic input; 5.5 V tolerant.
13	4B	input	Gate 4 input B. CMOS logic input; 5.5 V tolerant.
14	VCC	power_in	Positive supply, 1.65 V to 3.6 V for SN74LVC00A. Bypass with 100 nF to GND close to the pin.

CAD (KiCad official)

Symbol: SN74LVC00APWR
Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
3D model: TSSOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc00apwr.step`	194 KB	You want the bare part, or you mark your own boards.
`sn74lvc00apwr-etched.step`	2.6 MB	You want the part with `SN74LVC00APWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 662 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.
