Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Positive power supply; the power supply range is 1.8 V to 4.2 V over -40 °C to +85 °C, with an absolute maximum DC supply of -0.5 V to +5.25 V. |
| 2 | NO1 | passive | Data port (normally open) of switch 1, connected to COM1 when the select input is logic 1. |
| 3 | COM1 | passive | Common output/data port of switch 1; continuous DC current from COM to NC/NO is limited to ±300 mA. |
| 4 | IN1 | input | Logic control input for switch 1; it must be held between 0 V and VCC + 0.5 V, with maximum input voltage of +5.25 V, and the logic thresholds are given in the electrical characteristics. |
| 5 | NC1 | unconnected | Data port (normally closed) of switch 1, connected to COM1 when the select input is logic 0. |
| 6 | GND | power_in | Ground reference (0 V) for the device. |
