ANALOG DEVICES LTC2856IDD-2#PBF

LTC2856 is a low power, RS485/RS422 transceiver operating on 5V supplies at maximum data rates of 250kbps for low EMI. 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 ±15kV (human body model) on the transceiver interface pins without latchup or damage. Typical applications include low power RS485/RS422 transceiver, level translator, backplane transceiver.
