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.
