ANALOG DEVICES LTC2856CMS8-1#PBF

LTC2856CMS8-1#PBF is a low power, RS485/RS422 transceiver operating on 5V supplies. The receiver has a one-eighth unit load, supporting up to 256 nodes per bus, and a 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 these parts to withstand ±15KV (human body model) on the transceiver interface pins without latch-up or damage. It is used in applications such as low-power RS485/RS422 transceiver, level translator, backplane transceiver.
