LTC487CN#PBF, Differential Bus / Line Driver, RS422, RS485, 4 Drivers, 4.75 V to 5.25 V, 0 °C to 70 °C

LTC487 is a low power differential bus/line driver designed for multipoint data transmission standard RS485 applications with extended common mode range (-7V to 12V). It also meets RS422 requirements. The CMOS design offers significant power savings over its bipolar counterpart without sacrificing ruggedness against overload or ESD damage. The driver features 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. It is widely used in application such as low power RS485/RS422 drivers, level translator etc.
