    60V Fault-Protected 10Mbps Fail-Safe RS-485 Transceiver with 15kV ESD Protection MAX3443EASA


    ±60V Fault-Protected, 10Mbps, Fail-Safe RS-485 Transceiver

    with ±15kV ESD Protection


    General Description

    The MAX3443E fault-protected RS-485/RS-422 transceiver features ±60V protection from signal faults on communication bus lines. Each device contains one differential line driver with three-state output, and one differential line receiver with three-state input. The 1/4-unit-load receiver input impedance allows up to 128 transceivers on a single bus. The device operates from a 5V supply at data rates up to 10Mbps. True fail-safe inputs guarantee a logic-high receiver output when the receiver inputs are open, shorted, or connected to an idle data line.


    Hot-swap circuitry eliminates false transitions on the data cable during circuit initialization or connection to a live backplane. Short-circuit current limiting and thermal shutdown circuitry protect the driver against excessive power dissipation, and integrated ±15kV ESD protection eliminates costly external protection devices.


    The MAX3443E is available in 8-pin SO and PDIP packages, and is specified over commercial, industrial, and automotive temperature ranges.
