Pinout

Pin	Name	Type	Function
1	I/O1	bidirectional	Data line I/O1 is a TVS-protected line of the 4-line array, with 0.3 pF typical I/O-to-I/O capacitance and nA-level leakage stated in the features.
2	GND	power_in	Ground reference for the TVS array; the 300 W peak pulse power rating (8/20 µs) is specified between Vcc and GND.
3	I/O2	bidirectional	Data line I/O2 is a TVS-protected line of the 4-line array, rated for ESD of ±25 kV air and ±20 kV contact per IEC 61000-4-2.
4	I/O3	bidirectional	Data line I/O3 is a TVS-protected line of the 4-line array, with a 5 V low operating voltage stated in the features.
5	VCC	power_in	Power line pin of the TVS array; the datasheet's peak pulse power and clamping ratings are referenced to Vcc-GND.
6	I/O4	bidirectional	Data line I/O4 is a TVS-protected line of the 4-line array, with clamping voltage specified for 8/20 µs pulses up to 4.7 A.
