ITU Low Cost, 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 providesselective denial of power. IfthePBX
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 newdigital
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.
2. θJA is measured with the component mounted on an evaluation PC board in free air.
