ABSTRACT:
A CMOS off-chip driver circuit is provided which includes a first P-channel field effect transistor arranged in series with a second or pull-up P-channel transistor and a third P-channel transistor connected from the common point between the first and second transistors and the gate electrode of the first transistor. The first and second transistors are disposed between a data output terminal and a first voltage source having a supply voltage of a given magnitude, with the data output terminal also being connected to a circuit or system including a second voltage source having a supply voltage of a magnitude significantly greater than that of the given magnitude. In a more specific aspect of this invention, a fourth P-channel transistor, disposed in a common N-well with the other P-channel transistors, is connected at its source to the first voltage source and at its drain to the common N-well, with its gate electrode being connected to the data output terminal.
