Description
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.
