±40V Fault Protected and ±15kV ESD protected RS-485/RS-422 I/O pin. For parts

without the cable invert function - or if INV is low - B/Z is the inverting receiver input and

inverting driver output. If INV is high, B/Z is the non-inverting receiver input and the

non-inverting driver output. Pin is an input if DE = 0; pin is an output if DE = 1.
