No Internal Connection.
±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.

System power supply input (3V to 5.5V).
Receiver and driver Cable Invert (polarity selection) input. When driven high this pin
swaps the polarity of the driver output and receiver input pins. If unconnected
(floating) or connected low, normal RS-485 polarity conventions apply. Internally
pulled low.
