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 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 and LFCSP
packages.
