  • The ST485A is a low power, high speed transceiver for RS-485 and RS-422 communications. The device contains one driver and one receiver in half duplex configuration. The ST485A draws 3 mA (typ.) of supply current when unloaded or fully loaded with disabled drivers. It operates from a single 5 V supply.

    Driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that place the driver outputs into a high-impedance state. The receiver input has a fail-safe feature that guarantees a logic high output if both inputs are open circuit.
    The ST485A is designed for bi-directional data communications or multipoint bus transmission lines.

    主要特性

    • Latch-up free up to 500 mA
    • Current limiting and thermal shutdown for driver overload protection
    • Operate from single 5 supply
    • 70mV typical input hysteresis
    • Low supply current: 5 mA max
    • Designed for RS 485 interface applications
    • High data rate > 30 Mbps
    • Driver maintains high impedance in 3-state or with the power off
    • ±4 kV ESD protection
    • -7 to 12 common mode input voltage range
