4066G-S14-R from UTC Unisonic Tech, 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 IN/OUT A bidirectional Switch A bidirectional analog/digital signal terminal (paired with pin 2). When CONTROL A is high, this terminal is connected to pin 2 through the switch (RON ~80Ω @ VDD=15V).
2 OUT/IN A bidirectional Switch A bidirectional analog/digital signal terminal (paired with pin 1). Signals up to ±7.5V peak may pass when the switch is enabled by CONTROL A.
3 OUT/IN D bidirectional Switch D bidirectional analog/digital signal terminal (paired with pin 4). Connected to pin 4 through the switch when CONTROL D (pin 12) is high.
4 IN/OUT D bidirectional Switch D bidirectional analog/digital signal terminal (paired with pin 3). Signals up to ±7.5V peak may pass when CONTROL D is high.
5 CONTROL B input Digital control input for switch B. Logic-high (VIHC, typ. 2.75V @ VDD=5V) closes switch B connecting pins 8 and 9; logic-low opens it. Extremely high input impedance (~10^12 Ω typ.).
6 CONTROL C input Digital control input for switch C. Logic-high closes switch C connecting pins 10 and 11; logic-low opens it. Input current typ. ±10^-5 μA at VDD-VSS=15V.
7 VSS power_in Negative supply / ground reference. Typically tied to 0V for digital use, or to a negative rail (e.g. -5V) to allow bipolar analog signal switching. Absolute rating VSS = 0V reference.
8 IN/OUT B bidirectional Switch B bidirectional analog/digital signal terminal (paired with pin 9). Connected to pin 9 through the switch when CONTROL B (pin 5) is high.
9 OUT/IN B bidirectional Switch B bidirectional analog/digital signal terminal (paired with pin 8). Signals up to ±7.5V peak may pass when CONTROL B is high.
10 OUT/IN C bidirectional Switch C bidirectional analog/digital signal terminal (paired with pin 11). Connected to pin 11 through the switch when CONTROL C (pin 6) is high.
11 IN/OUT C bidirectional Switch C bidirectional analog/digital signal terminal (paired with pin 10). Signals up to ±7.5V peak may pass when CONTROL C is high.
12 CONTROL D input Digital control input for switch D. Logic-high closes switch D connecting pins 3 and 4; logic-low opens it. High input impedance (~10^12 Ω typ.).
13 CONTROL A input Digital control input for switch A. Logic-high closes switch A connecting pins 1 and 2; logic-low opens it. VILC max 1.5V and VIHC min 3.5V @ VDD=5V.
14 VDD power_in Positive supply voltage. Recommended operating range 3V to 15V (absolute max +18V). Sets the logic-high threshold for the CONTROL inputs and the peak analog signal swing referenced to VSS.
