This datasheet also covers the HC55120 variant, as both devices belong to the same low power unislic14 family and are provided as variant models within a single manufacturer datasheet.
Key Features
The UniSLIC14 is a family of Ultra Low Power SLICs. The feature set and common pinouts of the UniSLIC14 family positions it as a universal solution for: Plain Old Telephone Service (POTS), PBX, Central Office, Loop Carrier, Fiber in the Loop, ISDN-TA and NT1+, Pairgain and Wireless Local Loop. The UniSLIC14 family achieves its ultra low power operation through: Its automatic single and dual battery selection (based on line length) and battery tracking anti clipping to ensure the maximum loop co.
