Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1I/O | passive | Switch 1 bidirectional signal terminal; switch I/O voltage range is 0 to VCC. |
| 2 | 1O/I | passive | Switch 1 bidirectional signal terminal on the opposite side; switch I/O voltage range is 0 to VCC. |
| 3 | 2O/I | passive | Switch 2 bidirectional signal terminal; switch I/O voltage range is 0 to VCC. |
| 4 | 2I/O | passive | Switch 2 bidirectional signal terminal on the opposite side; switch I/O voltage range is 0 to VCC. |
| 5 | 2C | input | Control input for switch 2; high turns the switch on and low turns it off, and an unused input must be tied to VCC or GND. |
