FN4125.4

ITU Low Cos t, PABX SLIC With 40mA

Loop Feed

Features

• Low Cost Version of the HC-5504B

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.

• Capable of 5V or 12V (V +) Operation

• Monolithic Integrated Device

• DI High Voltage Process

• Compatible With Worldwide PBX Performance

Requirements

• Controlled Supply of Battery Feed Current for Short Loops

(41mA)

The SLIC also provides selective denial of power. If the PBX

system becomes overloaded during an emergency, the SLIC

will provide system protection by denying power to selected

subscriber loops.

• Internal Ring Relay Driver

• Allows Interfacing With Negative Superimposed Ringing

Systems

The Intersil SLIC is ideally suited for the design of new digital

PBX systems by eliminating bulky hybrid transformers.

• Low Power Consumption During Standby

• Switch Hook Ground Key and Ring Trip Detection
