LTC1485CS8#PBF

差分驱动器, RS422/RS485, 4.75V-5.25V电源, SOIC-8

The is a low power differential bus/line Transceiver designed for multipoint data transmission standard RS485 applications with extended common-mode range. The CMOS with Schottky design offers significant power savings over its bipolar counterpart without sacrificing ruggedness against overload or ESD damage. The driver and receiver feature three-state outputs with the driver outputs maintaining high impedance over the entire common-mode range. Excessive power dissipation caused by bus contention or faults is prevented by a thermal shutdown circuit which forces the driver outputs into a high impedance state. I/O pins are protected against multiple ESD strikes of over ±10kV. The receiver has a fail-safe feature which guarantees a high output state when the inputs are left open.
