LTC2855HGN#PBF

LTC2855HGN#PBF is a 3.3V 20Mbps RS485/RS422 transceiver with integrated switchable termination. The driver maintains a high output impedance over the entire common mode range when disabled or when the supply is removed. Excessive power dissipation caused by bus contention or a fault is prevented by current limiting all outputs and by a thermal shutdown. The LTC2855 to withstand ±15kV on the transceiver interface pins without latchup or damage. Application includes low power RS485/RS422 transceiver. level translator, backplane transceiver.
