A programmable output buffer providing variable drive strength and slew rate for a given noise limit that includes a driver stage that generates the output of the buffer and a plurality of selectively enabled switching elements, at least a predriver stage providing a plurality of selectable switching elements that enables the selected drive stage switching elements, and a selection means that enables the required predriver switching elements in the desired sequence to provide the desired drive strength and slew rate.
