ADI ADM3491EARZ-REEL7

收发器RS422，RS48510Mbps

Overview

The devices have a 12 kΩ receiver input impedance which allows up to 32 transceivers on a bus. Since only one driver should be enabled at any time, the output of a disabled or powered down driver is three-stated to avoid overloading the bus. 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 failsafe feature which 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 shutdown circuit. The parts are fully specified over the industrialtemperature ranges and are available in narrow 8-lead and 14-lead (ADM3491E) SOIC packages.
