74VHC08MX from onsemi, 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	A0	input	Gate 0 input A. CMOS logic input, 0-7V tolerant regardless of VCC. Must be held HIGH or LOW; may not float.
2	B0	input	Gate 0 input B. CMOS logic input, 0-7V tolerant regardless of VCC. Must be held HIGH or LOW; may not float.
3	O0	output	Gate 0 output = A0 AND B0. CMOS push-pull output; VOH ~ VCC-0.1V at IOH=-50uA, VOL ~ 0.1V; drives +/-8 mA at VCC=4.5V.
4	A1	input	Gate 1 input A. CMOS logic input, 0-7V tolerant regardless of VCC. Must be held HIGH or LOW; may not float.
5	B1	input	Gate 1 input B. CMOS logic input, 0-7V tolerant regardless of VCC. Must be held HIGH or LOW; may not float.
6	O1	output	Gate 1 output = A1 AND B1. CMOS push-pull output; drives +/-8 mA at VCC=4.5V.
7	GND	power_in	Ground reference (0 V). Common return for VCC.
8	O3	output	Gate 3 output = A3 AND B3. CMOS push-pull output; drives +/-8 mA at VCC=4.5V.
9	B3	input	Gate 3 input B. CMOS logic input, 0-7V tolerant regardless of VCC. Must be held HIGH or LOW; may not float.
10	A3	input	Gate 3 input A. CMOS logic input, 0-7V tolerant regardless of VCC. Must be held HIGH or LOW; may not float.
11	O2	output	Gate 2 output = A2 AND B2. CMOS push-pull output; drives +/-8 mA at VCC=4.5V.
12	B2	input	Gate 2 input B. CMOS logic input, 0-7V tolerant regardless of VCC. Must be held HIGH or LOW; may not float.
13	A2	input	Gate 2 input A. CMOS logic input, 0-7V tolerant regardless of VCC. Must be held HIGH or LOW; may not float.
14	VCC	power_in	Positive supply, 2.0 V to 5.5 V recommended (7.0 V absolute max). Bypass locally with 0.1 uF to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74vhc08mx.step`	195 KB	You want the bare part, or you mark your own boards.
`74vhc08mx-etched.step`	2.0 MB	You want the part with `74VHC08MX` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 521 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.
