ABSTRACT:
In an autoclear circuit for producing reset signals for performing an initializing operation of a system simultaneously with the turning on of the system power supply, a first reset signal is produced by a delay circuit when a quickly rising power supply voltage is supplied through the input terminal connected to the power supply, and a second reset signal is produced by a Schmitt circuit when a slowly rising power supply voltage is supplied to the input terminal. Reset signals corresponding to the rise characteristics of the power supply voltage are thus produced and applied to the output terminal of the autoclear circuit to initialize the system.
