ABSTRACT:
A semiconductor integrated circuit device has a circuit construction which is devised with an output circuit for feeding an output current to an operating supply voltage in response to an output signal of a current switch circuit responding to an input signal. A constant current element for producing the operating current of the current switch circuit is fed with a constant voltage through a resistance element. A capacitor is coupled between the input of the constant current element and the operating supply voltage so that it constructs a time constant circuit together with the resistance element. The time constant circuit has a time constant set longer than the period of the output signal of the output circuit.
