HC-5502B

Data Sheet February 1999

EIA/ITU PABX SLIC with 30mA Loop Feed

The Intersil SLIC incorporates many of the BORSHT functions on a single IC chip. This includes DC battery feed, a ring relay driver, supervisory and hybrid functions. This device is designed to maintain transmission performance in the presence of externally induced longitudinal currents. Using the unique Intersil dielectric isolation process, the SLIC can operate directly with a wide range of station battery voltages.

The SLIC also providesselective denial of power. IfthePBX system becomes overloadedduring an emergency,theSLIC will provide system protection by denying power to selected subscriber loops.

The Intersil SLIC is ideally suited forthe design of new digital PBX systems, by eliminating bulky hybrid transformers.
