FUNCTION
GND Ground connection.
A/Y ±16.5kV IEC61000 ESD Protected RS-485/RS-422 level, non-inverting receiver input and non-inverting driver output. Pin is an input
(A) if DE = 0; pin is an output (Y) if DE = 1. ISL3179E only
B/Z ±16.5kV IEC61000 ESD Protected RS-485/RS-422 level, inverting receiver input and inverting driver output. Pin is an input (B) if DE
= 0; pin is an output (Z) if DE = 1. ISL3179E only
A ±12kV HBM ESD Protected RS-485/RS-422 level, non-inverting receiver input. ISL3180E only
B ±12kV HBM ESD Protected RS-485/RS-422 level, inverting receiver input. ISL3180E only
Y ±12kV HBM ESD Protected RS-485/RS-422 level, non-inverting driver output. ISL3180E only
