A

RXP

VCC

N.C.

Noninverting Receiver Input

Receiver Input Resistors*

Noninverting Receiver Input and Noninverting Driver

Output

Receiver Phase. Connect RXP to GND, or leave uncon-

nected for normal transmitter phase/polarity. Connect to

VCC to invert the receiver phase/polarity:

Positive Supply 4.75V ≤ VCC ≤ 5.25V

Not Connected. Not internally connected.

*(MAX3089E only) In half-duplex mode, the driver outputs serve as receiver inputs. The full-duplex receiver inputs (A and B) will still

have a 1/8-unit load, but are not connected to the receiver.
