NAME
FUNCTION
1
——
SHDN
Shutdown. Drive SHDN high to enter low-power shutdown mode.
22
1
RO
Receiver Output. When RE is low and (A - B)
≥ -50mV, RO is high; if (A - B) ≤
-200mV, RO is low.
3
—
2
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.
4
—
3DE
Driver Output Enable. Drive DE high to enable driver output. These outputs
are high impedance when DE is low. Drive RE high and DE low to enter low-
power shutdown mode.
53
4
DI
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.

GND
Ground

——
TXP
Transmitter Phase. Connect TXP to GND, or leave unconnected for normal
transmitter phase/polarity. Connect TXP to VCC to invert the transmitter
phase/polarity. TXP has an internal 15A pulldown.

RXP
Receiver Phase. Connect RXP to GND, or leave unconnected for normal
receiver phase/polarity. Connect RXP to VCC to invert the receiver
phase/polarity. RXP has an internal 15A pulldown.
