EIA/ITU PABX SLIC with 30mA Loop Feed

Features

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 12V or 5V (V +) Operation

• Monolithic Integrated Device

• DI High Voltage Process

• Compatible With Worldwide PBX Performance

Requirements

• Controlled Supply of Battery Feed Current for Short Loops

(30mA)

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

• Low Power Consumption During Standby

• Switch Hook, Ground Key and Ring Trip Detection

Functions

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

PBX systems, by eliminating bulky hybrid transformers.

• Selective Denial of Power to Subscriber Loops
