RO
O
Receiver Output. When RE is low and if (A-
B)
≥ -50mV, RO is High. If (A-B) ≤ -200mV,
RO is Low.

3
RE
I
Receiver Output Enable. When RE is Low,
RO is enabled. When RE is High, RO is
high impedance. RE should be High and
DE should be low to enter shutdown mode.
RE is a hot-swap input.

-
4
DE
I
Driver Output Enable. When DE is High,
outputs are enabled. When DE is low, out-
puts are high impedance. DE should be low
and RE should be High to enter shutdown
mode. DE is a hot-swap input.

5
DI
I
Driver Input. With DE high, a low level on DI
forces Non-Inverting output low and invert-
ing output high. Similarly, a high level on DI
forces Non-Inverting output High and Invert-
ing output Low.
