EIA/ITU 24V PABX SLIC with 25mA

Loop Feed

The HC-5524 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 24V interface between

the traditional telephone subscriber pair (Tip and Ring) and

the low voltage ﬁltering and coding/decoding functions of the

line card. Together with a secondary protection diode bridge,

the device will withstand 500V induced surges, in plastic

packages. The SLIC also maintains speciﬁed transmission

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-5524 SLIC is ideally suited for line card designs in

PBX and DLC systems, replacing traditional transformer

solutions.
