GENERAL DESCRIPTION
The ADM488A and ADM489A 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 RS-485 and RS-422
standards of the Electronics Industries Association (EIA). Both
products contain a single differential line driver and a single
differential line receiver, making them suitable for full-duplex
data transfer. The ADM489A contains an additional receiver
and driver enable control.
The input impedance is 12 k, allowing 32 transceivers to be
connected on the bus. The ADM488A/ADM489A operate from
a single 5 V ± 10% power supply.

Excessive power dissipation that is 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.
The receiver contains a fail-safe feature that results in a logic
high output state if the inputs are unconnected (floating).
The ADM488A/ADM489A are fabricated on BiCMOS, an
advanced mixed technology process combining low power
CMOS with fast switching bipolar technology.
The ADM488A/ADM489A are fully specified over the industrial
temperature range and are available in SOIC and MSOP packages.
