LTC2852HMS#PBF developed by Linear Technology/Analog Devices is a type of low power, 20Mbps RS485/RS422 transceivers. When disabled or when the supply is removed, a high output impedance is maintained over the entire common mode range. Current limiting and thermal shutdown are able to prevent ecessive power dissipation caused by bus contention or a fault. Its failsafe feature ensures a high output state under conditions of floating or shorted inputs. The LTC2852HMS#PBF transceiver is available in the SO-14, MSOP-10, or DFN-10 package to save board space.
