RO
Receiver Output. When
RE
is low and (A - B)
≥
-50mV, RO is high; if (A - B)
≤
-200mV, RO is low.
Receiver Output Enable. Drive
RE
low to enable RO; RO is high impedance
when
RE
is high. Drive
RE
high and DE low to enter low-power shutdown mode.
Driver Output Enable. Drive DE high to enable driver output. The driver
outputs are high impedance when DE is low. Drive
RE
high and DE low to
enter low-power shutdown mode.
Driver Input. With DE high, a low on DI forces the noninverting output low and
the inverting output high. Similarly, a high on DI forces the noninverting output
high and the inverting output low.
Ground
Transmitter Phase. Connect TXP to GND, or leave unconnected for normal
transmitter phase/polarity. Connect TXP to V
CC
to invert the transmitter
phase/polarity. TXP has an internal 15μA pulldown.
Noninverting Driver Output
Inverting Driver Output
Inverting Receiver Input
Noninverting Receiver Input
Receiver Phase. Connect RXP to GND, or leave unconnected for normal
receiver phase/polarity. Connect RXP to V
CC
to invert the receiver
phase/polarity. RXP has an internal 15μA pulldown.
Positive Supply: +4.75V

to GND with a 0.1μF
capacitor.
