Abstract

A semiconductor integrated circuit receiving at its input pin the terminal voltage of a capacitor which is connected to a power source through a resistor so as to detect the level of the power voltage. The circuit is provided with a level shift circuit which shifts the incoming power voltage level by a predetermined value so that a reset signal is produced by detecting the output of the level shift circuit falling below the threshold level of a logic circuit.
