RO
Description
Receiver Output. When enabled, if A > B by 200 mV, then
RO = high. If A < B by 200 mV, then RO = low.
Receiver Output Enable. A low level enables the receiver
output, RO. A high level places it in a high impedance
state. If RE is high and DE is low, the device enters a low
power shutdown mode.
Driver Output Enable. A high level enables the driver differential
Output A and Output B. A low level places it in a high impedance
state. If RE is high and DE is low, the device enters a low power
shutdown mode.
Driver Input. With a half-duplex part when the driver is enabled, a
logic low on DI forces A low and B high while a logic high on
DI forces A high and B low. With a full-duplex part when the
driver is enabled, a logic low on DI forces Y low and Z high
while a logic high on DI forces Y high and Z low.
Ground.
Noninverting Driver Output.
