CD4078BPWR from Texas Instruments, in a TSSOP-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	K	output	NOR output. Low when any of the 8 inputs (A-H) is high; high only when all 8 inputs are low. CMOS push-pull.
2	A	input	Logic input A to the 8-input NOR/OR gate. High-impedance CMOS input.
3	B	input	Logic input B to the 8-input NOR/OR gate. High-impedance CMOS input.
4	C	input	Logic input C to the 8-input NOR/OR gate. High-impedance CMOS input.
5	D	input	Logic input D to the 8-input NOR/OR gate. High-impedance CMOS input.
6	E	input	Logic input E to the 8-input NOR/OR gate. High-impedance CMOS input.
7	VSS	power_in	Ground / negative supply. Typically 0V.
8	NC	unconnected	No internal connection. Leave floating or tie to any convenient node.
9	F	input	Logic input F to the 8-input NOR/OR gate. High-impedance CMOS input.
10	G	input	Logic input G to the 8-input NOR/OR gate. High-impedance CMOS input.
11	H	input	Logic input H to the 8-input NOR/OR gate. High-impedance CMOS input.
12	NC	unconnected	No internal connection. Leave floating or tie to any convenient node.
13	J	output	OR output. High when any of the 8 inputs (A-H) is high; low only when all inputs are low. CMOS push-pull.
14	VDD	power_in	Positive supply. Operating range 3V to 18V; absolute max 20V.

CAD (KiCad official)

Symbol: CD4078BPWR
Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
3D model: TSSOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cd4078bpwr.step`	194 KB	You want the bare part, or you mark your own boards.
`cd4078bpwr-etched.step`	2.5 MB	You want the part with `CD4078BPWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 623 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.
