ABSTRACT:
An integrated SLIC having input pins coupled to the wires of a two-wire telephone subscriber line is protected from excessive voltages on the line by reverse biassed 60 volt zener diodes connected between each input pin and ground, normally reverse biassed diodes within the integrated circuit connected between each input pin and the substrate of the integrated circuit, and a normally forward biassed diode connected between the substrate and a -48 volt (nominal) supply voltage.
