MC14070BDR2G 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 to XOR gate A; VIL/VIH scale with VDD (e.g. at VDD=5V, VIL<=1.5V, VIH>=3.5V). Double-diode protected to VSS and VDD.
2	IN2A	input	Gate A input 2. CMOS logic input to XOR gate A; paired with IN1A. Double-diode input protection.
3	OUTA	output	Gate A buffered output. XOR of IN1A and IN2A. Sources/sinks TTL-compatible drive (e.g. IOL >= 0.51 mA at VDD=5V, VOL=0.4V).
4	OUTB	output	Gate B buffered output. XOR of IN1B and IN2B. CMOS full-rail output (VOH within 0.05V of VDD, VOL within 0.05V of VSS unloaded).
5	IN1B	input	Gate B input 1. CMOS logic input to XOR gate B. Unused inputs must be tied to VDD or VSS.
6	IN2B	input	Gate B input 2. CMOS logic input to XOR gate B; paired with IN1B.
7	VSS	power_in	Negative supply / ground reference. All input and output voltages are referenced to VSS. Typically tied to 0 V (0 to -18 V relative to VDD).
8	IN1C	input	Gate C input 1. CMOS logic input to XOR gate C.
9	IN2C	input	Gate C input 2. CMOS logic input to XOR gate C; paired with IN1C.
10	OUTC	output	Gate C buffered output. XOR of IN1C and IN2C.
11	OUTD	output	Gate D buffered output. XOR of IN1D and IN2D.
12	IN1D	input	Gate D input 1. CMOS logic input to XOR gate D.
13	IN2D	input	Gate D input 2. CMOS logic input to XOR gate D; paired with IN1D.
14	VDD	power_in	Positive supply. Operating range 3.0 to 18 Vdc (absolute max -0.5 to +18 V). Decouple locally to VSS.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc14070bdr2g.step`	195 KB	You want the bare part, or you mark your own boards.
`mc14070bdr2g-etched.step`	2.8 MB	You want the part with `MC14070BDR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 690 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.
