2 I/O 2 passive Protected unidirectional data/interface line 2 of the 6-line TVS array; SMDA03-6 has a 3.3 V maximum standoff voltage (VWM) per line.
3 I/O 3 passive Protected unidirectional data/interface line 3 of the 6-line TVS array; SMDA03-6 has a 3.3 V maximum standoff voltage (VWM) per line.
4 I/O 4 passive Protected unidirectional data/interface line 4 of the 6-line TVS array; SMDA03-6 has a 3.3 V maximum standoff voltage (VWM) per line.
5 I/O 5 passive Protected unidirectional data/interface line 5 of the 6-line TVS array; SMDA03-6 has a 3.3 V maximum standoff voltage (VWM) per line.
6 GND power_in Common ground reference for the TVS array diodes, shown tied internally with the other GND pin in the circuit diagram.
7 GND power_in Common ground reference for the TVS array diodes, shown tied internally with the other GND pin in the circuit diagram.
8 I/O 6 passive Protected unidirectional data/interface line 6 of the 6-line TVS array; SMDA03-6 has a 3.3 V maximum standoff voltage (VWM) per line.
