ABSTRACT:
An input/output driver circuit which provides a buffer interface between a functional digital circuit and a common bus for other digital circuits achieves high levels of voltage tolerance and compliance, while requiring only two power supply pins, by using two PMOS switching transistors between the circuit's output line and an output power supply terminal, rather than only one. To turn the transistors OFF, the output power supply voltage is applied to the gate of one of them and the output line voltage to the gate of the other. This assures that at least one of the transistors is fully OFF when desired, whether or not the output line voltage exceeds the output power supply level.
