LTC2852HS#PBF

LTC2852HS#PBF is a low power, 20Mbps RS485/RS422 transceiver operating on 3.3V supply. Failsafe feature that guarantees a high output state under conditions of floating or shorted inputs. 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 up to ±15kV (human body model) on the transceiver interface pins without latchup or damage. Application includes low power RS485/RS422 transceiver, level translator, backplane transceiver.
