GENERAL DESCRIPTION
The ADM483 is a low power differential line transceiver suitable
for half-duplex data communication on multipoint bus trans-
mission lines. It is designed for balanced data transmission, and
complies with EIA Standards RS-485 and RS-422.The part
contains a differential line driver and a differential line receiver.
Both share the same differential pins, with either the driver or
the receiver being enabled at any given time.
The device has an input impedance of 12 kΩ, allowing up to
32 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. This high
impedance driver output is maintained over the entire
common-mode voltage range from –7 V to +12 V.
The receiver contains a fail-safe feature that results in a logic
high output state if the inputs are unconnected (floating).
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 by a thermal shutdown circuit.
The part is fully specified over the industrial temperature range,
and is available in an 8-lead SOIC package.
