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.

PIN FUNCTION DESCRIPTIONS
ORDERING GUIDE
PIN CONFIGURATION
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.
