LTC2858HMS-2#PBF

LTC2858HMS-2#PBF is a full duplex, low power, RS485/RS422 transceiver. 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 thermal shutdown. Enhanced ESD protection allows this part to withstand ±15KV (human body model) on the transceiver interface pins without latchup or damage. It is used in applications such as low power RS485/RS422 transceiver, level translator, backplane transceiver.
