产品概述

描述

The ST485ERB is a low-power transceiver for RS-485 and RS-422 communication. Each driver output and receiver input is protected against ±15 kV electrostatic discharge (HBM) ± 8 kV (IEC-1000-4-2 contact discharge) shocks, without latch-up. These parts contain one driver and one receiver.

This transceiver draws 300 µA (typ.) of supply current when unloaded or fully loaded with disabled drivers.

It operates from a single 5 V supply.

The driver is a short-circuit current which is limited and protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state.

The ST485ERB is designed for bi-directional data communication on multipoint bus transmission lines (half-duplex applications).

  • 所有功能

    • Low quiescent current: 300 µA
    • Designed for RS-485 interface applications
    • - 7 V to 12 V common mode input voltage range
    • Driver maintains high impedance in 3-state or with the power OFF
    • 70 mV typical input hysteresis
    • 30 ns propagation delay, 5 ns skew
    • Operates from a single 5 V supply
    • Current limiting and thermal shutdown for driver overload protection
    • ESD protection:
      • ± 15 kV (HBM)
      • ± 8 kV (IEC-1000-4-2 contact discharge)
    • Allows up to 64 transceivers on the bus
