Abstract

The present invention discloses an output buffer having a first and a second driver, wherein the drivers are used to drive the potential of an output end responding to the logic level of an input signal. The driving force of the second driver is larger than that of the first driver. Additionally, the output buffer has a control circuit used to detect the logic level variation of input signals. A control signal having a predetermined time duration and a specified potential level is produced according to the level variation of input signals. With said control signal, the second driver starts to drive the output end only after the level of input signals has varied for a predetermined time duration to speed the level variation of an output end.
