Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IO | bidirectional | Bidirectional ESD/transient protection line connected to IO; Pin1 or Pin2 to Pin3 reverse standoff is 12.0 V, breakdown is 13.3 to 16.3 V at 1 mA, and clamping voltage is 24.0 V at IPP 17 A. |
| 2 | IO | bidirectional | Bidirectional ESD/transient protection line connected to IO; Pin1 or Pin2 to Pin3 reverse standoff is 12.0 V, breakdown is 13.3 to 16.3 V at 1 mA, and clamping voltage is 24.0 V at IPP 17 A. |
| 3 | GND | power_in | Common ground reference for the protection; Pin3 to Pin1 or Pin2 reverse standoff is 7.0 V, breakdown is 7.5 to 9.8 V at 1 mA, and clamping voltage is 18.0 V at IPP 22 A. |
