RO
Receiver Output. When RE is low
and if (A – B) ≥ -40mV, RO is high.
If (A – B) ≤ - 200mV, RO is low.

RE
REREE
Receiver Output Enable. When RE
is low, RO is enabled. When RE
is high, RO is high impedance.
Drive RE 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. Drive DE 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 non-inverting
output low and inverting output
high. A high level on DI forces non-
inverting output high and inverting
output low.
