ANALOG DEVICES LTC2857IMS8-2#PBF

LTC2857IMS8-2#PBF is a slew rate limited 15kV RS485/RS422 transceiver. The receiver has a one-eighth unit load, supporting up to 256 nodes per bus, and a fail-safe 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 ±15kV (human body model) on the transceiver interface pins without latchup or damage. Application includes low power RS485/RS422 transceiver, level translator backplane transceiver.
