Receiver Output: If A > B by 200mV, RO will be high;
If A < B by 200mV, RO will be low.

—
Driver Output Enable. The driver outputs, Y and Z, are
enabled by bringing DE high. They are high imped-
ance when DE is low. If the driver outputs are enabled,
the parts function as line drivers. While they are high
impedance, they function as line receivers if

Driver Input. A low on DI forces output Y low and out-
put Z high. Similarly, a high on DI forces output Y high
and output Z low.
