US07714618B2 Output driver circuit with output preset circuit and controlling method thereof having lower power consumption 有权
具有输出预置电路的输出驱动电路及其具有较低功耗的控制方法

Output driver circuit with output preset circuit and controlling method thereof having lower power consumption
Abstract:
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.
Abstract(Chinese):

提供了输出驱动电路的输出预置电路的结构及其控制方法。 所提出的输出预置电路包括产生锁存器输出信号的锁存器和接收预设使能信号和锁存器输出信号的上拉电路，其中上拉电路将输出驱动器电路的输出电压从地电平 当预置使能信号处于低电平并且锁存器输出信号处于高电平时，变为第一电平。
