Abstract
The present invention is to provide an output circuit, for a semiconductor circuit, capable of increasing the rise or fall time of an output signal without reducing the operating frequency of the output circuit, and thus effectively preventing occurrence of a malfunction due to an undesired change in the output signal caused by ringing, noise, or reflection occurring at the transition of the output signal. In the structure of present invention, an output circuit for a semiconductor circuit includes an input circuit, an output circuit including a transistor, and a control signal control circuit that lies between the input circuit and output circuit, outputs a control signal for use in driving the transistor in the output circuit, and changes the control signal according to a function of time.
