摘要

4 input latched circuits 3b are arranged four input signals in the multi signal switch circuits which use IN1 - IN4. These 4 input latched circuits 3b are formed, the signal the inside one of IN1 of the aforementioned four - IN4 L , three taking H when, four NAND circuits 6 ' 'with. Each NAND circuit 6' 'with, as for the output, each, the input signal it is connected by one inside IN1 of the aforementioned four - IN4, it inputs three signals where other than of the signal which is connected to that output remains. Therefore, regarding the multi signal switch circuits which have the input signal of three or more, timing error between the multi signals which it should output is prevented effectively.
