GENERAL DESCRIPTION

The receiver contains a fail-safe feature that results in a logic

high output state if the inputs are unconnected (floating).

The ADM488 and ADM489 are low power, differential line

transceivers suitable for communication on multipoint bus

transmission lines. They are intended for balanced data

transmission and comply with both Electronics Industries

Association (EIA) RS-485 and RS-422 standards. Both products

contain a single differential line driver and a single differential

line receiver, making them suitable for full-duplex data transfer.

The ADM489 contains an additional receiver and driver enable

control.

The ADM488/ADM489 are fabricated on BiCMOS, an

advanced mixed technology process combining low power

CMOS with fast switching bipolar technology.

The ADM488/ADM489 are fully specified over the industrial

temperature range and are available in PDIP, SOIC, and TSSOP

packages.

The input impedance is 12 kΩ, allowing 32 transceivers to be

connected on the bus.

The ADM488/ADM489 operate from a single 5 V 1ꢀ0 power

supply. Excessive power dissipation caused by bus contention or

output shorting is prevented by a thermal shutdown circuit.

This feature forces the driver output into a high impedance state

if, during fault conditions, a significant temperature increase is

detected in the internal driver circuitry.
