ABSTRACT:
An improved logic circuit for switching noise reduction is disclosed. The logic circuit is provided between a voltage source line and a plurality of ground lines. The logic circuit according to the present invention changes connection to the ground line in response to a logic status change of an input signal by means of a switching circuit therein to isolate an input or output terminal from a switching noise on a predetermined ground line which tends to generate switching noise at the logic status change.
