SEMICONDUCTOR INTEGRATED CIRCUIT AND SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress power consumption at off-time, without spoiling fast operation using a low-threshold transistor (TR). SOLUTION: This semiconductor integrated circuit composed of a 1st TR with a 1st threshold which constitutes the semiconductor integrated circuit including a MOSFET is characterized in that at least one of 1st transistors TRL which is present between the power source and ground, the power source or ground and the output circuit to the semiconductor integrated circuit, or output circuits to the semiconductor integrated circuit and forms a current path is replaced with a transistor part, including a 2nd transistor TRH with a 2nd threshold higher than the 1st threshold.
