3.3 V, ±15 kV ESD-Protected, Half- and Full-Duplex, RS-485/RS-422 Transceivers

Analog Devices 

ADM3483E/ADM3486E/ADM3488E/ADM3490E/ADM3491E

GENERAL DESCRIPTION

(continued from Page 1)

The driver outputs of the ADM3483E/ADM3486E/

ADM3488E are slew rate limited, in order to reduce EMI

and data errors caused by reflections from improperly

terminated buses. The receiver has a fail-safe feature that

ensures a logic high output when the inputs are floating.

Excessive power dissipation caused by bus contention

or by output shorting is prevented with a thermal shut-

down circuit.

The parts are fully specified over the industrial temperature range

and are available in 8-lead and 14-lead narrow SOIC packages.
