CD4066BM96 from Texas Instruments, in a SOIC-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	SIG_A_IN/OUT	bidirectional	Switch A signal terminal (bilateral). One of the two analog/digital signal I/O pins of switch A; either pin can be used as input or output. Signal-level range VSS ≤ VIS ≤ VDD.
2	SIG_A_OUT/IN	bidirectional	Switch A signal terminal (bilateral). Complementary terminal of switch A; conducts to pin 1 when CONTROL A is high.
3	SIG_B_OUT/IN	bidirectional	Switch B signal terminal (bilateral). Conducts to pin 4 when CONTROL B is high.
4	SIG_B_IN/OUT	bidirectional	Switch B signal terminal (bilateral). Complementary terminal of switch B.
5	CONTROL_B	input	Digital control input for switch B. Logic 1 (VC = VDD) turns switch B on; logic 0 (VC = VSS) turns it off. VIH ≥ 3.5 V @ VDD=5 V (11 V min @ VDD=15 V); VIL ≤ 1 V @ VDD=5 V. Input impedance ~10^12 Ω; protected by CMOS protection network.
6	CONTROL_C	input	Digital control input for switch C. Logic 1 = switch on, logic 0 = switch off. High-impedance CMOS input (~10^12 Ω) with protection network.
7	VSS	power_in	Negative supply / ground reference. Signal-level lower bound (VSS ≤ VIS ≤ VDD). Typically 0 V for single-supply operation or a negative rail for bipolar analog switching.
8	SIG_C_IN/OUT	bidirectional	Switch C signal terminal (bilateral). Conducts to pin 9 when CONTROL C is high.
9	SIG_C_OUT/IN	bidirectional	Switch C signal terminal (bilateral). Complementary terminal of switch C.
10	SIG_D_OUT/IN	bidirectional	Switch D signal terminal (bilateral). Conducts to pin 11 when CONTROL D is high.
11	SIG_D_IN/OUT	bidirectional	Switch D signal terminal (bilateral). Complementary terminal of switch D.
12	CONTROL_D	input	Digital control input for switch D. Logic 1 = switch on, logic 0 = switch off. High-impedance CMOS input with protection network.
13	CONTROL_A	input	Digital control input for switch A. Logic 1 (VC = VDD) turns switch A on; logic 0 (VC = VSS) turns it off. High-impedance CMOS input with protection network.
14	VDD	power_in	Positive supply. Recommended operating range 3 V to 18 V (absolute max 20 V referenced to VSS). Also the upper signal-level bound (VSS ≤ VIS ≤ VDD) and the logic-high level for the CONTROL inputs.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cd4066bm96.step`	195 KB	You want the bare part, or you mark your own boards.
`cd4066bm96-etched.step`	2.8 MB	You want the part with `CD4066BM96` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 667 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.
