Abstract
An input buffer circuit is provided that has improved speed performance. The input buffer circuit has a voltage swing of V.sub.DD -V.sub.th to V.sub.SS. In so doing, the speed of the input buffer signal from input to output is significantly increased. In addition, the circuit also incorporates an additional current leaker transistor that limits the output high voltage from going above V.sub.DD -V.sub.th.
