Receiver Output. If A>B by
200mV, then RO = HIGH; If
A<B by 200mV, then
RO = LOW
Receiver Output Enable.
Low active input.
RO is high-Z when
RE = HIGH
Driver Output Enable.
The transmitter outputs, Y and
Z, are enabled when DE =
HIGH. The outputs are high-Z
when DE = LOW.
Driver Input. A low on DI
forces output Y low and output
Z high. A high on DI will bring
output Y high and output Z low
Analog Ground
