NAME
FUNCTION
FAULT
Fault output. 1 = fault; 0 = normal operation
A or B under the following conditions:
• A-B differential <200mV
• A shorted to B
• A shorted to a voltage within the common-mode range
(detected only when the driver is enabled)
• B shorted to a voltage within the common-mode range
(detected only when the driver is enabled)
• A or B outside the common-mode range

Receiver Output. If receiver enabled and (A-B) ≥ -50mV,
RO = high; if (A-B) ≤ -200mV, RO = low.
Receiver Output Enable. Pull RE low to enable RO.
Driver Output Enable. Pull DE low to enable the outputs
Force DE high to three-state the outputs. Drive RE and DE
high to enter low-power shutdown mode.
Driver/Receiver Output Enable. Pull DE/RE low to three-
state the driver output and enable RO. Force DE/RE high to
enable driver output and three-state RO
Driver Output Enable. Force DE high to enable driver. Pull
DE low to three-state the driver output. Drive RE high and
pull DE low to enter low-power shutdown mode.
Driver Input. A logic-low on DI forces the noninverting
output low and the inverting output high. A logic-high on
DI forces the noninverting output high and the inverting
output low.
J1708 Input. A logic-low on TXD forces outputs A and B
to the dominant state. A logic-high on TXD forces outputs
A and B to the recessive state.
