    _________________General Description
    The MAX1480A/MAX1480B/MAX1480C/MAX1490A/
    MAX1490B are complete, electrically isolated, RS-485/
    RS-422 data-communications interface solutions in a
    hybrid microcircuit. Transceivers, optocouplers, and a
    transformer provide a complete interface in a standard
    DIP package. A single +5V supply on the logic side pow-
    ers both sides of the interface.
    The MAX1480B/MAX1480C/MAX1490B feature reduced-
    slew-rate drivers that minimize EMI and reduce reflec-
    tions caused by improperly terminated cables, allowing
    error-free data transmission at data rates up to 250kbps.
    The MAX1480A/MAX1490A driver slew rate is not limited,
    allowing transmission rates up to 2.5Mbps. The
    MAX1480A/B/C are designed for half-duplex communi-
    cation, while the MAX1490A/B feature full-duplex com-
    munication.
    Drivers are short-circuit current limited and protected
    against excessive power dissipation by thermal shut-
    down circuitry that places the driver outputs into a high-
    impedance state. The receiver input has a fail-safe
    feature that guarantees a known output (RO low for the
    MAX1480A/B/C, RO high for the MAX1490A/B/C) if the
    input is open circuit.
    The MAX1480A/MAX1480B/MAX1480C/MAX1490A/
    MAX1490B typically withstand 1600V
    RMS
     (1 minute) or
    2000V
    RMS
     (1 second). Their isolated outputs meet all 
    RS-485/RS-422 specifications. The MAX1480A/B/C are
    available in a 28-pin DIP package, and the MAX1490A/B
    are available in a 24-pin DIP package.
