Product Summary

The LTC1481CS8#TR is an ultra-low power differential line transceiver designed for data transmission standard RS485 applications. It will also meet the requirements of RS422. The CMOS design offers significant power savings over its bipolar counterparts without sacrificing ruggedness against overload or ESD damage. Typical quiescent current is only 80mA while operating and less than 1mA in shutdown. The applications of the LTC1481CS8#TR include Battery-Powered RS485/RS422 Applications, Low Power RS485/RS422 Transceiver, Level Translator.
