Data Sheet
HC-5504B
July 1998 File Number 2886.5
EIA/ITU PABX SLIC with 40mA 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 provides selective denial of power. If the PBX
system becomes overloaded during an emergency, the SLIC
will provide system protection by denying power to selected
subscriber loops.
The Intersil SLIC is ideally suited for the design of new digital
PBX systems by eliminating bulky hybrid transformers.
