  L 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 pins—the industry’s
  highest protection level for an RS485 …
