GENERAL DESCRIPTION
The ADM3485E is a low power differential line transceiver
designed to operate using a single +3.3 V power supply. Low
power consumption makes it ideal for power sensitive applica-
tions. It is suitable for communication on multipoint bus trans-
mission lines. Internal protection against electrostatic discharge
(ESD) and electrical fast transient (EFT) allows operation in
electrically harsh environments.
It is intended for balanced data transmission and complies with
both EIA Standards RS-485 and RS-422. It contains a differen-
tial line driver and a differential line receiver, and is suitable for
half duplex data transfer.
The input impedance is 19 k
allowing up to 50 transceivers to
be connected on the bus.
Excessive power dissipation caused by bus contention or by
output shorting is prevented by a thermal shutdown circuit.
This feature forces the driver output into a high impedance
state if, during fault conditions, a significant temperature
increase is detected in the internal driver circuitry.
The receiver contains a fail-safe feature that results in a
logic high output state if the inputs are unconnected
(floating).
The ADM3485E is fabricated on BiCMOS, an advanced
mixed technology process combining low power CMOS
with fast switching bipolar technology.
The ADM3485E is fully specified over the industrial tem-
perature range and is available in 8-lead DIP and SOIC
packages.
