RE
Receiver Output Enable. A low level enables the receiver output, whereas
a high level places the receiver output in a high impedance state.

DE
Driver Output Enable. A logic high enables the differential driver outputs,
A and B, whereas a logic low places the differential driver outputs in a
high impedance state.

DI
Driver Input. When the driver is enabled, a logic low on DI forces Pin A low
and Pin B high, whereas a logic high on DI forces Pin A high and Pin B low.
