ADM3485EARZ

Product Summary

The ADM3485EARZ is a low power differential line transceiver designed to operate using a single +3.3 V power supply. Low power consumption makes it ideal for power sensitive applications. The ADM3485EARZ is suitable for communication on multipoint bus transmission lines. Internal protection against electrostatic discharge (ESD) and electrical fast transient (EFT) allows operation in electrically harsh environments. The applications of the ADM3485EARZ include Telecommunications, DTE-DCE Interface, Packet Switching, Local Area Networks, Data Concentration, Data Multiplexers, Integrated Services Digital Network (ISDN), AppleTalk and Industrial Controls.
