  • 5 volt CMOS driver circuit for driving 3.3 volt line
    Patent number: 5786720
    Abstract: A driver circuit that is powered by a power supply voltage has an output terminal, and includes a pull-up transistor for pulling the output terminal up toward the power supply voltage. A voltage divider that is connected across the power supply voltage has a tap connected in circuit to an input of the pull-up transistor and includes variable resistance elements whose resistance varies together with a threshold voltage of the pull-up transistor for limiting a voltage at the output terminal to within a predetermined range that is lower than the power supply voltage.
