Function
Receiver Output: If A
>
B by 200 mV, RO will be high; If A
<
B by 200mV, RO will be low. RO
will be high also if the inputs (A and B) are open (non-terminated)
Receiver Output Enable: RO is enabled when RE is low; RO is in TRI-STATE when RE is high
Driver Output Enable: The driver outputs (A and B) are enabled when DE is high; they are in
TRI-STATE when DE is low. Pins A and B also function as the receiver input pins (see below)
Driver Input: A low on DI forces A low and B high while a high on DI forces A high and B low
when the driver is enabled
