Abstract
An output buffer circuit including different arrangements of output devices selectable by circuitry which tests the load characteristics to provide different buffer drive strengths, and different paths having different current carrying characteristics for enabling the output devices selectable by the circuitry which tests the load characteristics to vary the slew rate of the output devices to best match the load.
