GENERAL DESCRIPTION

The ADM485E/ADM487E/ADM1487E are 5 V, low power

data transceivers with 15 kV ESD protection suitable for half-

duplex communication on multipoint bus transmission lines.

They are designed for balanced data transmission and comply

with Telecommunication Industry Association/Electronics Indus-

tries Association (TIA/EIA) standards RS-485 and RS-422. The

ADM487E and ADM1487E have a 1/4 unit load receiver input

impedance that allows up to 128 transceivers on a bus, whereas

the ADM485E allows up to 32 transceivers on a bus. Because

only one driver is enabled at any time, the output of a disabled or

power-down driver is three-stated to avoid overloading the bus.

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 output

shorting is prevented with a thermal shutdown circuit.

The parts are fully specified over the industrial temperature

ranges and are available in 8-lead SOIC packages.
