GENERAL DESCRIPTION
The ADM4850/ADM4851/ADM4852/ADM4853/ADM4854/ADM4855/ADM4856/ADM4857 are differential line transceivers suitable for high speed half- and full-duplex data communication on multipoint bus transmission lines. They are designed for balanced data transmission and comply with EIA Standards RS-485 and RS-422. The ADM4850/ADM4851/ADM4852/ADM4853 are half duplex transceivers that share differential lines and have separate enable inputs for the driver and receiver. The full-duplex ADM4854/ADM4855/ADM4856/ADM4857 transceivers have dedicated differential line driver outputs and receiver inputs.
The parts have a 1/8-unit-load receiver input impedance, which allows up to 256 transceivers on one bus. Because only one driver should be enabled at any time, the output of a disabled or powered-down driver is three-stated to avoid overloading the bus.
The receiver inputs have a true fail-safe feature, which ensures a logic high output level when the inputs are open or shorted. This guarantees that the receiver outputs are in a known state before communication begins and when communication ends. The driver outputs are slew-rate limited to reduce EMI and data errors caused by reflections from improperly terminated buses. Excessive power dissipation caused by bus contention or by output shorting is prevented with a thermal shutdown circuit.
The parts are fully specified over the commercial and industrial temperature ranges and are available in 8-lead SOIC, LFCSP (ADM4850/ADM4851/ADM4852/ADM4853), and MSOP (ADM4850 only) packages.
