RO
Receiver Output. When
RE
is low and A - B > -50mV, RO will be high; if A - B
≤
-200mV,
RO will be low.

RE
DE
Receiver Output Enable. Drive
RE
low to enable RO.
Driver Output Enable. Drive DE high to enable driver outputs.
Driver Input. With DE high, a low on DI forces the noninverting output low and the inverting
output high; with DI high, outputs reverse.
