Receiver Output. With the receiver output enabled (RE low), RO is high if
A > B by 200mV or when A and B are not connected, and RO is low if A < B
by 200mV.
Receiver Output Enable. When RE is low, RO is enabled. When RE is high, RO
is high impedance. If RE is high and DE is low, the MAX1482/MAX1483 enter
a low-power (0.1µA) shutdown state.
Driver Output Enable. The driver outputs, A and B, (Y and Z for the MAX1482)
are enabled by bringing DE high. When DE is low, the driver outputs are high
impedance, and the devices can function as line receivers if RE is low. If RE is
high and DE is low, the parts will enter a low-power (0.1µA) shutdown state. If
the driver outputs are enabled, the devices function as line drivers.
Driver Input. With DE high, a low on DI forces output Y low and output Z high,
and a high on DI forces output Y high and output Z low.
