  • The ST4485EB device is a ± 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 ST4485EB transmits and receives at a guaranteed data rate of at least 20 Mbps.
    All transmitter outputs and receiver inputs are protected to ± 15 kV using “Human Body Model”.
    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 human body model
      • ± 8 kV IEC 1000-4-2 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 20 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
    • Wide operating temperature range: -40 to +105 °C
