Abstract
The present invention facilitates communication of signals from circuitry implemented with a first CMOS technology requiring a first voltage level supply for operation to circuitry implemented with a second CMOS technology requiring a second voltage level supply for operation, wherein the first and second voltage level supplies are not equal. The present invention receives from the circuitry implemented with a first CMOS technology a signal which has a first voltage level that is not acceptable for input into the circuitry implemented with a second CMOS technology. This signal is converted to a second voltage level that is acceptable for input into the circuitry implemented with a second CMOS technology, and then transmitted to the circuitry implemented with a second CMOS technology requiring a second voltage level supply for operation.
