HC-5509A1

SLIC

Subscriber Line Interface Circuit

Description

The HC-5509A1 telephone Subscriber Line Interface Circuit
integrates most of the BORSCHT functions on a monolithic
IC. The device is manufactured in a Dielectric Isolation (DI)
process and is designed for use as a high voltage interface
between the traditional telephone subscriber pair (Tip and
Ring) and the low voltage filter ing and coding/decoding func­tions of the line card. Together with a secondary protection
diode bridge and “feed” resistors, the device will withstand
1000V lightning induced surges, in plastic packages. The
SLIC also maintains specified transmission performance in
the presence of ex ternally induced longi tudinal currents. The
BORSCHT functions that the SLIC provides are:

• Battery Feed with Subscriber Loop Current Limiting

• Overvoltage Pro tection

• Ring Relay Driver

• Supervisory Signaling Functions

• Hybrid Functions (with External Op-Amp)

• Test (or Batter y R eversal) Relay Driver

In addition, the SLIC provides selective denial of power to
subscriber loops, a programmable subscriber loop current
limit from 20 to 60mA, a thermal shutdo wn with an alarm out­put and line fault protection. Switch hook detection, ring trip
detection and ground key detection functions are also incor­porated in the SLIC devic e.

The HC-5509A1 SLIC is ideally suited for line card designs
in PBX and CO systems, replacing traditional transformer
solutions.
