DESCRIPTION
The LTC®487 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.
