  • CMOS low power mixed voltage bidirectional I/O buffer
    Patent number: 5300835
    Abstract: This invention describes the design and implementation of a low power CMOS bidirectional I/O buffer that translates low voltage core logic level signals into the highest logic level signals to drive the final output stage which outputs a selectable logic level signal. The invention further translates input signals of a variety of logic levels into low voltage core logic level signals. In either case, AC and DC power consumption is minimized in a mixed power supply environment that requires voltage translation to represent the proper binary logic levels.
