R (Pin 2): Receiver Output. If A > B by 200mV, R will be

high. If A < B by 200mV, then R will be low.

D (Pin 3): Driver Input. A low on D forces the driver outputs

A low and B high. A high on D will force A high and B low.

GND (Pin 4): Ground Connection.

Y (Pin 5): Driver Output.

Z (Pin 6): Driver Output.

B (Pin 7): Receiver Input.

A (Pin 8): Receiver Input.
