Product Summary
The LTC1480CS8#TR is an ultra-low power differential line transceiver which provides full RS485 compatibility while operating from a single 3.3V supply. It is designed for data transmission standard RS485 applications with extended common-mode range (12V to -7V). It also meets the requirements of RS422 and features high speed operation up to 2.5Mb/s. The CMOS design offers significant power savings without sacrificing ruggedness against overload or ESD damage. Typical quiescent current is only 300μA while operating and 1μA in shutdown. The applications of the LTC1480CS8#TR include Battery-Powered RS485/RS422 Applications, Low Power RS485/RS422 Transceiver, Level Translator.
