ABSTRACT:
A common cell for use as an input/output circuit in a CMOS integrated circuit having a P-channel transistor structure having a plurality of individual P-channel transistors, an N-channel transistor structure having a plurality of individual N-channel transistors and an I/O pad. The sources, drains and gates of the individual P-channel and N-channel transistors are connected to terminals. The various terminals and the I/O pad may be selectively connected in various ways to form various input/output circuits, as desired.
