GENERAL DESCRIPTION
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
duplex transceivers that share differential lines and have separate
enable inputs for the driver and receiver. The full-duplex
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 pow-
ered-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 only) packages.
