The LTC2852 is low power, 20Mbps RS485/RS422 transceiver operating on 3.3V supplies. The receiver has a one-eighth unit load supporting up to 256 nodes per bus (C-, I-grade), 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 up to ±15kV (human body model) on the transceiver interface pins without latchup or damage.
