DESCRIPTION  
The ST SLIC KIT (L3000S/L3030)is a set of solid  
statedevicesdesignedto integratemain of the fun-  
ctions needed to interface a telephoneline. It con-  
sists of 2 integrated devices : the L3000S line  
interfacecircuit and the L3030control unit.  
Thiskit performsthe main featuresof the BORSHT  
functions:  
Thiskit is fabricatedusing a 140VBipolartechnolo-  
gy for L3000Sand a 12VBipolar I2L technologyfor  
L3030.  
L3030 is available PLCC44 and L3000S in both  
FLEXIWATT15andPowerSO-20forsurfacemount  
application.  
This kit is suitable for all the following applications:  
C.O.(CentralOffice),DLC(DigitalLoopCarrier)and  
high range PABX (Private Automatic Branch Ex-  
change).
