GENERAL DESCRIPTION
The ADM4850−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−ADM4853 are half-duplex transceivers, which
share differential lines and have separate enable inputs for the driver and
receiver. The full-duplex ADM4854−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. Since 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 and LFCSP
packages.
