Abstract
A method and apparatus for providing a high speed tristate buffer. The buffer includes a p-channel pull-up transistor and a transfer gate. The source of the transistor is coupled to a voltage supply. The drain of the transistor is coupled to the buffer output. The gate of the transfer gate is coupled to a first clock source. The input to the transfer gate is a second clock source, and the output of the transfer gate is coupled to the gate of the p-channel transistor.
