Product Summary
The LE75183ADSC is a Line Card Access Switch (LCAS). The LE75183ADSC is a family of monolithic solid-state switches that is designed to provide both power ringing access and test access on the analog line card. These devices, while not a pin-for-pin replacement for the traditional electromechanical relay (EMR) solution, provide the equivalent switching functionality. The LE75183ADSC is meant as a solid-state alternative to the EMRs. The applications of the LE75183ADSC include Central office, DLC, PBX, DAML, HFC/FITL.
