A clear signal generating circuit for initializing a logic circuit upon the application of power to the logic circuit. The generator circuit comprises a level detection circuit for generating a detection signal when the power supply voltage reaches or exceeds a predetermined value, a counter circuit which commences to count in response to the detection signal and which generates a trigger pulse upon reaching a predetermined count and a status storage circuit which is placed in a first state in response to the occurrence of the detection signal and placed in a second state in response to the trigger pulse. The output of the status storage circuit is utilized as the generator circuit output.
