Abstract
PURPOSE: To obtain surely only a true value as a logical output by controlling the turning-on and off of a switching element according to true and false signals outputted from an integrated circuit which sends the logical output.
CONSTITUTION: Integrated circuit blocks 31, 32, etc., generate binary logical outputs and true and false signals of logic 0 and 1, which indicate that signals are ture or false, according to partial defects at a production time, etc. Consequently, when logical outputs of blocks 31 and 32 are false signals, transistors 37 and 38 become conductive, and logical output of blocks 31 and 32 become a reference potential forcedly and become logical 0, and only true values are surely obtained as a logical output by OR of logical operation circuit 39 formed by an OR circuit.
