MC14066BDTR2G from onsemi, 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 | IN1 | bidirectional | Analog/digital switch terminal A of switch 1. Bilateral pin (IN/OUT interchangeable). When CONTROL 1 = VDD the switch is ON and pin 1 is connected to pin 2 through Ron (typ 250 Ω at VDD=5 V). |
| 2 | OUT1 | bidirectional | Analog/digital switch terminal B of switch 1. Bilateral pin (IN/OUT interchangeable). Connected to pin 1 through the switch when CONTROL 1 is high. |
| 3 | OUT2 | bidirectional | Analog/digital switch terminal B of switch 2. Bilateral pin; connected to pin 4 through Ron when CONTROL 2 is high. |
| 4 | IN2 | bidirectional | Analog/digital switch terminal A of switch 2. Bilateral pin; connected to pin 3 through Ron when CONTROL 2 is high. |
| 5 | CONTROL2 | input | Digital control for switch 2. Logic 0 (VSS) turns the switch OFF; logic 1 (VDD) turns it ON. Triple-diode protected input; VIH >= 3.5 V at VDD=5 V, VIL <= 1.5 V. |
| 6 | CONTROL3 | input | Digital control for switch 3. Logic 0 = OFF, logic 1 = ON. Triple-diode protected CMOS input. |
| 7 | VSS | power_in | Negative supply / ground reference. All control-input and switch voltages are referenced to VSS. Supply range VDD-VSS = 3.0 to 18 V. |
| 8 | IN3 | bidirectional | Analog/digital switch terminal A of switch 3. Bilateral pin; connected to pin 9 through Ron when CONTROL 3 is high. |
| 9 | OUT3 | bidirectional | Analog/digital switch terminal B of switch 3. Bilateral pin; connected to pin 8 through Ron when CONTROL 3 is high. |
| 10 | OUT4 | bidirectional | Analog/digital switch terminal B of switch 4. Bilateral pin; connected to pin 11 through Ron when CONTROL 4 is high. |
| 11 | IN4 | bidirectional | Analog/digital switch terminal A of switch 4. Bilateral pin; connected to pin 10 through Ron when CONTROL 4 is high. |
| 12 | CONTROL4 | input | Digital control for switch 4. Logic 0 = OFF, logic 1 = ON. Triple-diode protected CMOS input. |
| 13 | CONTROL1 | input | Digital control for switch 1. Logic 0 = OFF, logic 1 = ON. Triple-diode protected CMOS input. |
| 14 | VDD | power_in | Positive supply. VDD-VSS range 3.0 to 18 Vdc; absolute max +18 V. Decouple to VSS with 100 nF near the pin. |
