ABSTRACT:
A complementary field effect transistor integrated circuit includes an input buffer, internal high density logic circuitry having a collapsed guard ring structure associated therewith, an internal power source which provides operating voltage for the internal high density logic lower than the junction reverse breakdown voltage of the collapsed guard ring structure, and an output level shifter circuit. The output level shifter circuit and input buffer, and internal power source have a conventional non-collapsed guard ring structure associated therewith.
