HCF40106YM013TR from STMicroelectronics, in a SOP-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	Schmitt trigger input A for inverter 1. Input voltage range 0 to VDD (recommended). Positive trigger threshold VP typ. 2.9 V @ VDD=5 V; negative trigger threshold VN typ. 1.9 V @ VDD=5 V. Protected by COS/MOS protection network.
2	G	output	Inverter 1 output (G = /A). Standard symmetrical CMOS output; IOH typ. -3.2 mA @ VDD=5 V, IOL typ. 1 mA @ VDD=5 V. VOH ≥ 4.95 V and VOL ≤ 0.05 V at VDD = 5 V with
3	B	input	Schmitt trigger input B for inverter 2. Same electrical characteristics as input A. Protected by COS/MOS protection network (diodes to VDD and VSS with series resistor).
4	H	output	Inverter 2 output (H = /B). Standard symmetrical CMOS output; drive characteristics identical to output G.
5	C	input	Schmitt trigger input C for inverter 3. Same electrical characteristics as input A. Protected by COS/MOS protection network.
6	I	output	Inverter 3 output (I = /C). Standard symmetrical CMOS output; drive characteristics identical to output G.
7	VSS	power_in	Negative supply / ground reference. All voltages in the datasheet are referenced to VSS. Typically tied to 0 V.
8	J	output	Inverter 4 output (J = /D). Standard symmetrical CMOS output; drive characteristics identical to output G.
9	D	input	Schmitt trigger input D for inverter 4. Same electrical characteristics as input A. Protected by COS/MOS protection network.
10	K	output	Inverter 5 output (K = /E). Standard symmetrical CMOS output; drive characteristics identical to output G.
11	E	input	Schmitt trigger input E for inverter 5. Same electrical characteristics as input A. Protected by COS/MOS protection network.
12	L	output	Inverter 6 output (L = /F). Standard symmetrical CMOS output; drive characteristics identical to output G.
13	F	input	Schmitt trigger input F for inverter 6. Same electrical characteristics as input A. Protected by COS/MOS protection network.
14	VDD	power_in	Positive supply voltage. Recommended range 3 V to 20 V; absolute maximum -0.5 V to +22 V. Should be bypassed to VSS with a decoupling capacitor near the pin.

Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
3D model: SOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`hcf40106ym013tr.step`	195 KB	You want the bare part, or you mark your own boards.
`hcf40106ym013tr-etched.step`	3.1 MB	You want the part with `HCF40106YM013TR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 779 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.
