Abstract
A high speed true/complement driver circuit is disclosed wherein the time interval between the address and memory select pulses are minimized by utilizing a high speed enhancement/depletion mode inverter pair followed by a clocked signal isolation stage. A pair of enhancement mode/depletion mode inverters connected in cascade configuration serves to generate the true and complement output signals which are isolated from noise at the input line by a symmetric pair of clocked FETs.
