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 en-
abled a logic Low on DI forces A low
and B high while a logic High on DI
forces A high and B low.

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 ADM1486 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!
