Product Summary

The L3037FN-B6 subscriber line interface circuit is a bipolar device in 70V technology developed for central office / loop carrier and private applications. The L3037FN-B6 is pin to pin and function compatible with L3035/36. One particular pin (reserved in L3035/36) is now used for reverse polarity transition time programming. The line polarity transition is not affecting the AC signal transmission that can continue also during the line voltage transition. L3037FN-B6 is available in two different package options: PLCC44 and PQFP44 (10 x 10mm).
