    • A buffer driving capability control device is provided which can suppress occurrence of radiated noise due to a load driven by large driving power in the case where loads differing in driving power are connected to one terminal. The device includes an output buffer which can switch between the driving capability for driving a load requiring large driving power and the driving capability for driving a load requiring small driving power, and also includes a control period for driving the load requiring the large driving power and a control period for driving the load requiring the small driving power, and during the respective control periods, switches the driving capability of the output buffer to the ones suitable for the corresponding loads.
    • 提供一种缓冲器驱动能力控制装置,其在驱动功率不同的负载连接到一个端子的情况下,可以抑制由于大驱动力驱动的负载引起的辐射噪声的发生。 该装置包括输出缓冲器,其可以在驱动需要大驱动功率的负载的驱动能力和用于驱动需要较小驱动功率的负载的驱动能力之间切换,并且还包括用于驱动需要较大驱动力的负载的控制周期,以及 用于驱动需要较小驱动力的负载的控制周期,并且在各个控制周期期间,将输出缓冲器的驱动能力切换到适合于相应负载的驱动能力。
