SLIC Subscriber Line Interface Circuit

The Intersil SLIC incorporates many of the BORSHT
function on a single IC chip.ThisincludesDCbattery 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 overloadedduringanemergency, 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 h ybrid transf ormers.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
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.
