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, …
