MC14050BDR2G from onsemi, in a SOIC-16. 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	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).
2	OUTA	output	Noninverting buffer A output. Follows the logic level presented on INA (pin 3). Drives up to ~3.2 mA sink at VDD = 5.0 V, VOL <= 0.4 V.
3	INA	input	Buffer A input. VIN may exceed VDD (up to 18 V) for level-shifting from a higher voltage domain down to VDD-referenced CMOS/TTL.
4	OUTB	output	Noninverting buffer B output. Follows INB (pin 5).
5	INB	input	Buffer B input. VIN may exceed VDD (up to 18 V) for high-to-low level conversion.
6	OUTC	output	Noninverting buffer C output. Follows INC (pin 7).
7	INC	input	Buffer C input. VIN may exceed VDD (up to 18 V) for high-to-low level conversion.
8	VSS	power_in	Ground / negative supply reference. All voltages in the datasheet are referenced to VSS.
9	IND	input	Buffer D input. VIN may exceed VDD (up to 18 V) for high-to-low level conversion.
10	OUTD	output	Noninverting buffer D output. Follows IND (pin 9).
11	INE	input	Buffer E input. VIN may exceed VDD (up to 18 V) for high-to-low level conversion.
12	OUTE	output	Noninverting buffer E output. Follows INE (pin 11).
13	NC	unconnected	No internal connection. Datasheet states pins 13 and 16 are not connected internally; connections to this terminal will not affect circuit operation.
14	INF	input	Buffer F input. VIN may exceed VDD (up to 18 V) for high-to-low level conversion.
15	OUTF	output	Noninverting buffer F output. Follows INF (pin 14).
16	NC	unconnected	No internal connection. Datasheet states pins 13 and 16 are not connected internally; connections to this terminal will not affect circuit operation.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc14050bdr2g.step`	217 KB	You want the bare part, or you mark your own boards.
`mc14050bdr2g-etched.step`	3.0 MB	You want the part with `MC14050BDR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 746 faces against 267 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.
