  • Patent number: 8299836
    Abstract: In a level shift circuit, when a power-source voltage variation dV/dt of a high voltage side occurs and influences on a logic level of a circuit, the passing through of a malfunction signal is masked and prevented in the first and second logic circuits, by a signal from a time-constant generation circuit or a portion where a power voltage variation occurs in advance, by utilizing the fact that this variation occurs both at a set side and a reset side. When the power source voltage variation dV/dt is generated at a high voltage side, sufficient allowance in the timing of this masking prevents an erroneous signal from being transmitted to a flip-flop, and a control signal is transmitted from a low voltage side circuit not giving malfunction to a high voltage side circuit, even when there is a production variation in each element in semiconductor processes.
