A logic circuit combines a plurality of pass-transistor logic trees and a multiple-input logic gate for receiving intermediate logic signals from the respective pass-transistor logic trees, and can express a complex logical operation while decreasing the number of stages in pass-transistor logic trees and improving operation speed. Even a logical operation that cannot be expressed efficiently by a known or conventional pass-transistor logic circuit can be expressed efficiently with performance higher than that of a known CMOS logic circuit. Furthermore, when a static feedthrough current of the multiple-input logic gate is suppressed, power consumption can be reduced. In some embodiments, since circuitry for suppressing a static feedthrough current of the multiple-input logic gate is arranged so that a probability of occurrence of logical collision with a preceding stage will decrease or will be nil, power consumption can further be reduced.
