Half-/Full-Duplex Select Pin. Connect H/
F
to V
CC
for half-
duplex mode; connect to GND or leave unconnected for
full-duplex mode.

RO
Receiver Output. When
RE
is low and if (A - B)
≥
-50mV,
RO is high; if (A - B)
≤
-200mV, RO is low.

RE
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.
RE
is a hot-swap
input (see the
Hot-Swap Capability
section for details).

DE
Driver Output Enable. Drive DE high to enable driver
outputs. These outputs are high impedance when DE is
low. Drive
RE
high and DE low to enter low-power
shutdown mode. DE is a hot-swap input (see the
Hot-
Swap Capability
section for details).

Slew-Rate Limit Selector Pin. Connect SRL to ground for
16Mbps communication rate; connect to V
CC
for 500kbps
communication rate. Leave unconnected for 250kbps
communication rate.
Ground
Transmitter Phase. Connect TXP to ground or leave
floating for normal transmitter phase/polarity. Connect to
V
CC
to invert the transmitter phase/polarity.
