摘要

In order to suppress an instantaneous carrying current (surge current) and power supply noise caused by the instantaneous carrying current (the surge current), the power supply cutoff structure of a semiconductor integrated circuit device comprises a switching circuit for controlling a power supply to a controlled circuit. The switching circuit includes a plurality of transistors each having a different current capability. The transistors are sequentially provided with a certain regularity, including from a low current capability transistor up to a high current capability transistor.
