Data Sheet July 1998 File Number

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.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operationofthe
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTES:

1. Absolute maximum ratings are limiting values, applied individually, beyond which the serviceability of the circuit may be impaired.
Functional operability under any of these conditions is not necessarily implied.
