Isolated RS-485 TransceiversIsolated RS-422/RS-485 Transceivers

NVE's award-winning IL400- and IL3000-Series single-chip isolated transceivers dramatically reduce chip count and board area compared to traditional optocouplers. Unique QSOP and 0.15" SOIC packages reduce board area even more.

The parts feature:

QSOP; 0.15" and 0.3"-Wide 16-pin SOIC
3 V to 5.5 V Power Supplies
Digital and Passive Input Versions

PROFIBUS Version Available
Up to 40 Mbps
44000 Year Barrier Life
