Product Summary
The LTC1485CS8 is a differential bus transceiver, designed for multipoint data transmission standard RS485 application with extended common-mode range (12V to 7V). It also meets the requirements of RS422.The CMOS with Schottky design offers significant power saving over its bipolar counterpart without sacrificing ruggedness against overload or ESD damage.The applications of the LTC1485CS8 include low power RS485/RS422 transceiver, level translator.
