  DESIGN FEATURES L High Speed Low Power RS485
  Transceivers with Integrated
  Switchable Termination
  by Ray Schuler and Steven Tanghe Introduction
  The LTC2859 and LTC2861 combine
  a logic-selectable integrated termination resistor with a rugged 20Mbps
  RS485/RS422 transceiver, providing a single die impedance-matched
  network solution in a tiny package.
  The low power driver features logicselectable reduced-slew rate mode for
  operation below 250kbps with low EMI
  emissions. The 1/8-unit load receiver
  provides a failsafe output over the full
  RS485 common mode range for up to
  256 nodes. Both receiver inputs and
  driver outputs feature robust ESD
  protection exceeding В±15kV. The half
  duplex LTC2859 is available in a 3mm
  Г— 3mm DFN, while the full duplex
  LTC2861 is available in both 4mm Г—
  3mm DFN and 16-pin SSOP packages
  (see photo in Figure 1). Block diagrams
  for the LTC2859 and LTC2861 are
  shown in Figure 2. Figure 1. Photograph of the LTC2861 SSOP, …
