NAME
FUNCTION
1
RO
Receiver Output. If the receiver is enabled and (VA - VB)
-50mV,
RO = high; if (VA - VB)
-200mV, RO = low.
2
RE
Receiver Output Enable. Pull
RE low to enable 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.
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. For normal operation,
bypass VCC to GND with a 0.1μF ceramic capacitor. For full ESD
protection, bypass VCC to GND with 1μF ceramic capacitor.

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.
—
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.
