Abstract
An output buffer circuit is provided which significantly reduces ground/Vcc bounce and glitches of signals provided to an integrated circuit. The circuit includes a plurality of transistors for providing a drive potential at the output of the device. The transistors are coupled such that they increase in size from the input to the output of the output buffer circuit. A control circuit provides control signals for sequentially turning off the transistors from the largest to smallest device thereby substantially reducing the Vcc bounce and glitches of the signals provided to the integrated circuit by the output buffer circuit.
