NAME
FUNCTION
1
—
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
2
1
RO
Receiver Output. If receiver enabled and (A-B)
-50mV,
RO = high; if (A-B)
-200mV, RO = low.
—
2
RE
Receiver Output Enable. Pull
RE low to enable RO.
—
3
DE
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.
3
—
DE/RE
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.
—
3
—
DE
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.
4
—
DI
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.
—
4
TXD
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.
5
GND
Ground
6
A
Noninverting Receiver Input/Driver Output
7
B
Inverting Receiver Input/Driver Output
8
VCC
Positive Supply, VCC = +4.75V to +5.25V
