## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I/O1 | passive | I/O protection line 1 (unidirectional TVS channel), 5V working voltage, ±30kV IEC 61000-4-2 air and contact ESD. |
| 2 | GND | power_in | Common return pin of the five-line TVS array, shared by all channels; not listed as an I/O pin in Note 1. |
| 3 | I/O2 | passive | I/O protection line 2 (unidirectional TVS channel), 5V reverse working voltage maximum. |
