MC74ACT08DR2G 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	1A	input	Gate 1 input A. TTL-compatible logic input (VIH min 2.0 V, VIL max 0.8 V at VCC = 4.5-5.5 V). AND-combined with 1B to drive output 1Y.
2	1B	input	Gate 1 input B. TTL-compatible logic input. AND-combined with 1A to drive output 1Y.
3	1Y	output	Gate 1 output. Y = A AND B. Push-pull CMOS output; sources/sinks 24 mA (IOH = -24 mA, IOL = 24 mA at VCC = 4.5 V).
4	2A	input	Gate 2 input A. TTL-compatible logic input. AND-combined with 2B to drive output 2Y.
5	2B	input	Gate 2 input B. TTL-compatible logic input. AND-combined with 2A to drive output 2Y.
6	2Y	output	Gate 2 output. Y = A AND B. Push-pull CMOS output rated 24 mA source/sink.
7	GND	power_in	Ground reference (0 V) for all four gates and internal logic.
8	3Y	output	Gate 3 output. Y = A AND B. Push-pull CMOS output rated 24 mA source/sink.
9	3B	input	Gate 3 input B. TTL-compatible logic input. AND-combined with 3A to drive output 3Y.
10	3A	input	Gate 3 input A. TTL-compatible logic input. AND-combined with 3B to drive output 3Y.
11	4Y	output	Gate 4 output. Y = A AND B. Push-pull CMOS output rated 24 mA source/sink.
12	4B	input	Gate 4 input B. TTL-compatible logic input. AND-combined with 4A to drive output 4Y.
13	4A	input	Gate 4 input A. TTL-compatible logic input. AND-combined with 4B to drive output 4Y.
14	VCC	power_in	Positive supply voltage. ACT recommended operating range 4.5-5.5 V (absolute max 7.0 V). Bypass with a 0.1 uF ceramic capacitor close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc74act08dr2g.step`	195 KB	You want the bare part, or you mark your own boards.
`mc74act08dr2g-etched.step`	2.8 MB	You want the part with `MC74ACT08DR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 708 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.
