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. Applications
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.
