DESCRIPTION
The LTC® 486 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 counterpart without sacrifi cing ruggedness
against overload or ESD damage.
