PURPOSE:To prevent generation of noise waveform except an expected waveform by using a multi-input logic element including an inverter for an operation means so as to form a logic circuit. CONSTITUTION:Input logic signals A, B, D are inputted directly and input logic signals C, E are inputted via inverters 12, 13 to a gate of a multi-input NAND 14, which applies logic operation and the output is an operation result Y. Through the constitution above, since the logic operation is applied by using the multi-input logic element, no delay time is caused to each input signal and the operation is applied different from the use of plural less-input logic elements. Thus, the generation of noise waveforms other than the expected value such as spike waveform is prevented as the output waveform, the malfunction of the multi-input logic circuit is prevented and high speed stable logic operation is attained. |
