LTC2852HDD#PBF

LTC2852 is a full duplex, low power, 20Mbps RS485/RS422 transceiver operating on 3.3V supplies. The receiver has a one-eight unit load supporting upto 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. It is used in application such as low power RS485/RS422 transceiver, level translator, backplane transceiver etc.

• 3.3V supply voltage
