OUTPUT DRIVER CIRCUIT WITH OUTPUT PRESET CIRCUIT AND CONTROLLING METHOD THEREOF HAVING LOWER POWER CONSUMPTION

摘要

The configurations of an output preset circuit for an output driver circuit and the controlling methods thereof are provided. The proposed output preset circuit includes a latch generating an latch output signal and a pull-up circuit receiving an preset enable signal and the latch output signal, in which the pull-up circuit increases an output voltage of the output driver circuit from a ground level to a first level when the preset enable signal is at a low level and the latch output signal is at the high level.
