To minimize the amount of input-output wiring required between circuits and modules, multilevel busses are used where four distinct voltage level states substitute for the common binary (two-state) levels. By this means two circuit outputs can share a common line. The push-pull driver circuit described performs the output function in such a multilevel arrangement and does it with a minimum of circuit components and area requirements of the semiconductor chip.
