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!

*Stresses above those listed under Absolute Maximum Ratings may cause permanent
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.

PIN FUNCTION DESCRIPTION
Pin Mnemonic
Function
1
RO
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.
Ground Connection, 0 V.
Noninverting Receiver Input A/Driver
Output A.
Inverting Receiver Input B/Driver
Output B.
Power Supply, 5 V ± 5%.
