EIA/ITU PABX SLIC with 40mA 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.  
• Pin for Pin Replacement for the HC-5504  
• Capable of 5V or 12V (V +) Operation  
B
• 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  
Functions

• Selective Denial of Power to Subscriber Loops
