CMOS SEMICONDUCTOR LOGIC CIRCUIT WITH MULTIPLE INPUT GATES

A semiconductor logic circuit includes a number of gate circuits and a voltage supply. Each of the gate circuits includes a series circuit comprising the same number of transistors of one conductivity type connected in series, and a parallel circuit comprising the same number of transistors of a different conductivity type connected in parallel. The series and parallel circuits are connected in series between a voltage supply and ground. The semiconductor logic circuit includes the same number of input pins, and an output pin connected in common to all of the gate circuits. Each of the input pins is connected to a different one of the transistors in the series circuit and to a different one of the transistors in the parallel circuit of each of the gate circuits. The control electrode of the k-th transistor from the end of each series circuit closer to the voltage supply is connected to a different one of the input pins, and the control electrode of the m-th transistor from the end of each parallel circuit closer to the input pins is connected to a different one of the input pins.
