Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I/O1 | passive | ESD-protected high-speed I/O channel 1 (typ. 1.0pF, max 1.5pF), clamped to VSS with ±10A 8/20µs surge rating and ±30kV IEC 61000-4-2 protection. |
| 2 | VSS | power_in | Ground reference (VSS) for the TVS array; all I/O and VCC clamping is referenced to this pin. |
| 3 | I/O2 | passive | ESD-protected high-speed I/O channel 2 (typ. 1.0pF, max 1.5pF), clamped to VSS with ±10A 8/20µs surge rating and ±30kV IEC 61000-4-2 protection. |
| 4 | I/O3 | passive | ESD-protected high-speed I/O channel 3 (typ. 1.0pF, max 1.5pF), clamped to VSS with ±10A 8/20µs surge rating and ±30kV IEC 61000-4-2 protection. |
| 5 | VCC | power_in | Positive supply/rail pin for the steering diodes, with 5.5V max operating voltage and ±12A 8/20µs surge rating VCC to VSS. |
| 6 | I/O4 | passive | ESD-protected high-speed I/O channel 4 (typ. 1.0pF, max 1.5pF), clamped to VSS with ±10A 8/20µs surge rating and ±30kV IEC 61000-4-2 protection. |
