LвЂ‰DESIGN FEATURES Rugged 3.3V RS485/RS422
Transceivers with Integrated
Switchable Termination
by Steven Tanghe and Ray Schuler Introduction
Medium and high speed RS485 networks must be terminated to avoid
data-corrupting reflections. This
means a termination resistor is placed
at each end of the bus. Of course, if
the network is expanded or reconfigured, the termination resistors must
also move. The 3.3V LTC2854 and
LTC2855 transceivers eliminate the
cumbersome task of shuffling termination resistors. These devices have
an integrated termination resistor
connected across the receiver inputs
that can be enabled or disabled with
simple logical control of an input
pin, making network configuration
and reconfiguration a snap. These
devices come in tiny packages and are
extremely robust, withstanding ESD
strikes of up to В±25kV HBM (LTC2854)
on the line I/O pinsвЂ”the industryвЂ™s
highest protection level for an RS485 …
