*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. 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.
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.
Ground Connection, 0 V.
Noninverting Receiver Input A/Driver
Output A.
Inverting Receiver Input B/Driver Output B.
Power Supply, 5 V ± 5%.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADM1485 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
WARNING!
