The ADM483E is a 5 V, low power data transceiver with ±15 kV ESD protection suitable for half-duplex communication on multipoint bus transmission lines. The ADM483E is designed for balanced data transmission and complies with TIA/EIA Standards RS-485 and RS-422, which allow up to 32 transceivers on a bus.

The ADM483E has a low current shutdown mode in which it consumes only 0.1 μA.

Because only one driver is enabled at any time, the output of a disabled or power-down driver is three-stated to avoid overloading the bus.

Drivers are short-circuit current-limited and are protected against excessive power dissipation by thermal shutdown circuitry that places their outputs into a high impedance state. The receiver input has a fail-safe feature that guarantees a logic high output if the input is open circuit.

The ADM483E is fully specified over the industrial temperature ranges and is available in 8-lead SOIC_N packages.

APPLICATIONS

  • Low power RS-485 systems

Product Detail

The EVAL-RS485HDEBZ allows quick and easy evaluation of half-duplex RS-485 transceivers with standard 8-lead SOIC footprints. The evaluation board allows interfacing via screw terminal block to digital I/O for driver input (DI), receiver output (RO), driver enable (DE) and receiver output (RO). Bus signals A and B (half-duplex bus) can be connected to a bus screw terminal block. One or two termination resistors can be connected to A and B via jumper settings, in order to evaluation the half-duplex RS-485 driver and receiver. Footprints are provided for pull-up and pull-down (biasing resistors) on the bus.

Devices for evaluation on the board must be ordered separately.
