The LTC2852CDD#PBF is a low power RS485/RS422 Transceiver operating on 3.3V 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 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 on the transceiver interface pins without latch-up or damage.
