CD40107BM96 from Texas Instruments, in a SOIC-8. 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 to the first 2-input NAND stage.
2	1B	input	Gate 1 input B. CMOS logic input to the first 2-input NAND stage.
3	1C	output	Gate 1 open-drain NAND output (C = NOT(A AND B)). N-channel open-drain output capable of sinking large currents; requires an external pull-up to the desired load rail. Sink capability typ. tens of mA at VDD=10 V.
4	NC	unconnected	No internal connection. Leave floating or tie to a convenient net; not internally bonded.
5	2C	output	Gate 2 open-drain NAND output (C = NOT(A AND B)). N-channel open-drain output capable of sinking large currents; requires an external pull-up to the desired load rail.
6	2B	input	Gate 2 input B. CMOS logic input to the second 2-input NAND stage.
7	2A	input	Gate 2 input A. CMOS logic input to the second 2-input NAND stage.
8	VSS	power_in	Negative supply / ground reference. Typically 0 V.
14	VDD	power_in	Positive supply voltage, 3 V to 15 V (absolute max 18 V). Bypass with a local ceramic capacitor to VSS.

CAD (KiCad official)

Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
3D model: SOIC-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cd40107bm96.step`	122 KB	You want the bare part, or you mark your own boards.
`cd40107bm96-etched.step`	2.4 MB	You want the part with `CD40107BM96` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 578 faces against 147 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.
