STMicroelectronics L3037
The L3037 subscriber line interface circuit is a bipolar device in 70V technology developed for central office / loop carrier and private applications. The L3037 is pin to pin and function compatible with L3035/36. The line polarity transition is not affecting the AC signal transmission that can continue also during the line voltage transition.L3037 is available in two different package options: PLCC44 and PQFP44 (10 x 10mm).| Part No. | L3037 |
