*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute maximum ratings for
extended periods of time may affect device reliability.

Receiver Output. High when A > B by 200 mV or low when A < B by 200 mV.
Receiver Output Enable. With RE low, the receiver output RO is enabled. With RE high, the output goes
high impedance. If RE is high and DE low, the ADM3485E enters a shutdown state.

Driver Output Enable. A high level enables the driver differential outputs, A and B. A low level places it in a
high impedance state.
Driver Input. 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.
