ADM483E:  5 V, ±15 kV ESD Protected, Slew Rate Limited, Low Power, Half Duplex RS-485/RS-422 Transceiver

Product Details


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.

Solving Isolation Challenges in Industrial Automation
This webcast will discuss the role isolation plays in providing protection and reducing the system bit-error-rate, using the specific design challenges of an RS-485 network. Topics to be covered in this presentation will include: Why and when one should isolate, Types of isolation and their advantages, Design Considerations for an RS-485 node (and how this translates to design considerations for signal isolation) as well as many other topics.
