ADM483 Datasheet PDF

●The ADM483EARZ is a low power Data Transceiver with ±15kV 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 0.1µA. 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 logic high output if the input is open circuit.
