Abstract
An input signal processing circuit formed as an integrated circuit is provided with power supply terminals of plus and minus potentials, a voltage dividing terminal connected to a voltage dividing point between the power supply terminals, and an input terminal applied thereto with an external operation signal. A discriminator circuit is included in the input signal processing circuit to determine whether a signal potential applied to the input terminal is above or below the divided voltage potential and to switch over an operating state of a circuit block contained within the input signal processing circuit to another operating state depending on the results of the determination.
