Abstract
A logic circuit includes a plurality of input terminals (IN.sub.1, IN.sub.2, . . . ), an output terminal (OUT), a load (L), and at least two driver circuits (D.sub.1, D.sub.2, . . . ). Each of the driver circuits includes a plurality of gates connected in series, each gate being driven by one of the potentials at the input terminals. In addition, the first gates (Q.sub.11, Q.sub.22, . . . or Q.sub.11 ', Q.sub.22 ', . . . ) of the driver circuit connected directly to the output terminal are driven by different potentials at the input terminals.
