LTC486IN#PBF

LTC486IN#PBF is a quad low power RS485 driver. It is a low power differential bus/line driver designed for multipoint data transmission standard RS485 applications with extended common-mode range (12V to -7V). It also meets RS422 requirements. The CMOS design offers significant power savings over its bipolar counter part 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. Application includes low power RS485/RS422 drivers, level translator.
