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.

PIN FUNCTION DESCRIPTION

Pin Mnemonic

Function

1

R O

Receiver Output. When enabled if A >B

by 200 mV, then RO = High. If A < B

by 200 mV, then RO = Low.

2

RE

Receiver Output Enable. A low level

enables the receiver output, RO. A high

level places it in a high impedance state.

3

D E

Driver Output Enable. A high level

enables the driver differential outputs, A

and B. A low level places it in a high

impedance state.

4

D I

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.
