RXP
Receiver Phase. Connect RXP to GND or leave
unconnected for normal transmitter phase/polarity.
Connect to VCC to invert receiver phase/polarity.

N.C.
No Connect. Not internally connected. Can be
connected to GND.
*
MAX3079E only. In half-duplex mode, the driver outputs serve as receiver inputs. The full-duplex receiver inputs (A and B) still have a
1/8-unit load, but are not connected to the receiver.
