MC14081BDR2G 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	IN1A	input	Gate A input 1. CMOS logic input, VIL max 1.5 V @ VDD=5 V, VIH min 3.5 V @ VDD=5 V. Unused inputs of AND gates must be tied to VDD.
2	IN2A	input	Gate A input 2. CMOS logic input paired with IN1A to produce OUTA = IN1A AND IN2A.
3	OUTA	output	Gate A buffered output. OUTA = IN1A AND IN2A. Capable of driving two low-power TTL loads or one low-power Schottky TTL load over the rated temperature range.
4	OUTB	output	Gate B buffered output. OUTB = IN1B AND IN2B.
5	IN1B	input	Gate B input 1. CMOS logic input, paired with IN2B.
6	IN2B	input	Gate B input 2. CMOS logic input, paired with IN1B.
7	VSS	power_in	Negative supply / ground reference for the package. All voltages in the datasheet are referenced to VSS. Typically tied to 0 V.
8	IN1C	input	Gate C input 1. CMOS logic input, paired with IN2C.
9	IN2C	input	Gate C input 2. CMOS logic input, paired with IN1C.
10	OUTC	output	Gate C buffered output. OUTC = IN1C AND IN2C.
11	OUTD	output	Gate D buffered output. OUTD = IN1D AND IN2D.
12	IN1D	input	Gate D input 1. CMOS logic input, paired with IN2D.
13	IN2D	input	Gate D input 2. CMOS logic input, paired with IN1D.
14	VDD	power_in	Positive supply voltage. Operating range 3.0 V to 18 V (absolute max -0.5 V to +18 V referenced to VSS). Bypass with a local decoupling capacitor to VSS.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc14081bdr2g.step`	195 KB	You want the bare part, or you mark your own boards.
`mc14081bdr2g-etched.step`	2.9 MB	You want the part with `MC14081BDR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 712 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.
