  • The ST3485EB/EC/EI/EIY device is ±15 kV ESD protected, 3.3 V low power transceiver for RS-485 and RS-422 communications. The device contains one driver and one receiver in half duplex configuration.

    The ST3485E device transmits and receives at a guaranteed data rate of at least 12 Mbps.
    All transmitter outputs and receiver inputs are protected to ±15 kV IEC 61000-4-2 air discharge.
    The driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high impedance state.

    Key Features

    • ESD protection
      • ±15 kV IEC 61000-4-2 air discharge
      • ±8 kV IEC 61000-4-2 contact discharge
    • Operate from a single 3.3 V supply - no charge pump required
    • Interoperable with 5 V logic
    • 1 µA low current shutdown mode max.
    • Guaranteed 12 Mbps data rate
    • -7 to 12 V common mode input voltage range
    • Half duplex versions available
    • Industry standard 75176 pinout
    • Current limiting and thermal shutdown for driver overload protection
    • Guaranteed high receiver output state for floating inputs with no signal present
    • Allow up to 64 transceivers on the bus
    • Available in SO8 package
    • Automotive grade (ST3485EIY)
