## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | input | Digital switch control input; IN=0 turns S1 ON and S2 OFF, IN=1 turns S1 OFF and S2 ON, with VINH min 2.4 V and VINL max 0.8 V at VDD=5 V. |
| 2 | VDD | power_in | Positive supply pin, operating range 1.8 V to 5.5 V (absolute maximum -0.3 V to +7 V). |
| 3 | GND | power_in | Ground, 0 V. |
| 4 | S1 | passive | Source terminal that can be used as an input or output; connected to D when IN=0. |
| 5 | D | passive | Drain terminal that can be used as an input or output; continuous current limited to 30 mA. |
| 6 | S2 | passive | Source terminal that can be used as an input or output; connected to D when IN=1. |
