Receiver Output. When A > B by 200 mV,
RO = high. If A < B by 200 mV, RO = low.
Driver Input. A logic Low on DI forces Y low
and Z high while a logic High on DI forces Y
high and Z low.

No Connect. No connections
are required to this pin.
Receiver Output. When
enabled if A > B by 200 mV
then RO = high. If A < B by
200 mV then RO = low.
Receiver Output Enable. A
low level enables the receiver
output, RO. A high level
places it in a high impedance
state.
Driver Output Enable. A
high level enables the driver
differential outputs, Y and Z.
A low level places it in a high
impedance state.
Driver Input. When the
driver is enabled, a logic Low
on DI forces Y low and Z
high, while a logic High on
DI forces Y high and Z low.
