CD40106BPWR 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	A	input	Channel A Schmitt-trigger inverter input. Accepts input from VSS to VDD; switches with hysteresis (typ 0.9 V at VDD = 5 V, 2.3 V at 10 V, 3.5 V at 15 V).
2	G	output	Channel A inverted output (G = /A). CMOS push-pull output referenced between VSS and VDD.
3	B	input	Channel B Schmitt-trigger inverter input.
4	H	output	Channel B inverted output (H = /B). CMOS push-pull output.
5	C	input	Channel C Schmitt-trigger inverter input.
6	I	output	Channel C inverted output (I = /C). CMOS push-pull output.
7	VSS	power_in	Ground / negative supply reference. All voltages in the datasheet are referenced to VSS.
8	J	output	Channel D inverted output (J = /D). CMOS push-pull output.
9	D	input	Channel D Schmitt-trigger inverter input.
10	K	output	Channel E inverted output (K = /E). CMOS push-pull output.
11	E	input	Channel E Schmitt-trigger inverter input.
12	L	output	Channel F inverted output (L = /F). CMOS push-pull output.
13	F	input	Channel F Schmitt-trigger inverter input.
14	VDD	power_in	Positive supply. Recommended operating range 3 V to 18 V (absolute max 20 V). Decouple locally to VSS.

3D model: TSSOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cd40106bpwr.step`	194 KB	You want the bare part, or you mark your own boards.
`cd40106bpwr-etched.step`	2.7 MB	You want the part with `CD40106BPWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 671 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.
