## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I/O1 | passive | TVS protected I/O line 1, steered by diodes to the common GND node, with 5V max reverse working voltage and ±30kV IEC61000-4-2 ESD rating. |
| 2 | GND | power_in | Common ground node of the 4-line TVS array to which all four I/O protection diodes return. |
| 3 | I/O2 | passive | TVS protected I/O line 2, steered by diodes to the common GND node, with 5V max reverse working voltage and ±30kV IEC61000-4-2 ESD rating. |
| 4 | I/O3 | passive | TVS protected I/O line 3, steered by diodes to the common GND node, with 5V max reverse working voltage and ±30kV IEC61000-4-2 ESD rating. |
| 5 | I/O4 | passive | TVS protected I/O line 4, steered by diodes to the common GND node, with 5V max reverse working voltage and ±30kV IEC61000-4-2 ESD rating. |
