Abstract
Provided is a logic circuit comprising: a switch portion that includes one or more switching devices configured to be turned on and off in accordance with an input signal and is configured to generate an output signal with a logical value according to an operating state of the switching devices; and a clamp portion configured to clamp a voltage of the output signal, of a case where the logical value of the output signal is logic H. The switch portion may be arranged between an output line and a reference potential line, and the clamp portion may be arranged in parallel with the switch portion, between the output line and the reference potential line. The logic circuit may include a current suppression portion configured to suppress a current flowing through the clamp portion, when the logical value of the output signal is logic H.
