Description
The HC-5509B3999-003 telephone Subscriber Line Inter-
face Circuit integrates most of the BORSCHT functions on a
monolithic IC. The device is manufactured in a Dielectric Iso-
lation (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 filtering and cod-
ing/decoding functions of the line card. Together with a sec-
ondary protection diode bridge and “feed” resistors, the
device will withstand 1000V lightning induced surges, in
plastic packages. The SLIC also maintains specified trans-
mission performance in the presence of externally induced
longitudinal currents. The BORSCHT functions that the SLIC
provides are:
Battery Feed with Subscriber Loop Current Limiting
Overvoltage Protection
Ring Relay Driver
Supervisory Signaling Functions
Hybrid Functions (with External Op-Amp)
Test (or Battery Reversal) Relay Driver
In addition, the SLIC provides selective denial of power to
subscriber loops, a programmable subscriber loop current
limit from 20mA to 60mA, a thermal shutdown 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 device.
The HC-5509B3999-003 SLIC is ideally suited for line card
designs in PBX and CO systems, replacing traditional
transformer solutions.
