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. When RE is low, RO is enabled.
When RE is high, RO is high impedance. RE should be
high and DE low to enter shutdown mode. RE is a hot-
swap input.

DE
Driver Output Enable. When DE is high, outputs are
enabled. When DE is low, outputs are high impedance. DE
should be low and RE high to enter shutdown mode. DE is
a hot-swap input.

DI
Driver Input. With DE high, a low level on DI forces
noninverting output low and inverting output high. Similarly,
a high level on DI forces noninverting output high and
inverting output low.
