Part Number : HC9P5504B-9
Function : EIA/ITU PABX SLIC with 40mA Loop Feed
Package : SOIC 24 Pin Type
Maker : Intersil
Pinouts : 
Description :
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.
