Industrial controls
The ADM3491 is intended for balanced data transmission and
complies with both EIA Standards RS-485 and RS-422. It
contains a differential line driver and a differential line receiver,
making it suitable for full-duplex data transfer.
The input impedance is 19 kΩ, 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 a significant temperature increase is
detected in the internal driver circuitry during fault conditions.
The receiver contains a fail-safe feature that results in a logic
high output state, if the inputs are unconnected (floating).
The ADM3491 is fabricated on BiCMOS, an advanced mixed
technology process combining low power CMOS with fast
switching bipolar technology.
The ADM3491 is fully specified over the industrial temperature
range and is available in DIP and SOIC packages, as well as the
space-saving TSSOP package.
GENERAL DESCRIPTION
The ADM3491 is a low power, differential line transceiver
designed to operate using a single 3.3 V power supply. Low
power consumption, coupled with a shutdown mode, makes it
ideal for power-sensitive applications. It is suitable for commu-
nication on multipoint bus transmission lines.
