Function
Receiver Output: If A
>
B by 200 mV, RO will be high; If A
<
B by 200 mV, 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-STATEwhen RE
*
is high
Driver Output Enable: The driver outputs (A and B) are enabled when DE is high; they are in
TRI-STATETRI-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
Ground
Non-inverting Driver Output and Receiver Input pin. Driver output levels conform to RS-485
