Abstract: A load driving circuit comprising: a bias current circuit configured to generate a bias current having a current value corresponding to a level of a control signal; a control circuit configured to control the level of the control signal so that the bias current is increased and thereafter decreased, when an input signal reaches one logic level; and a driving circuit configured to raise an output voltage for driving a load to a higher logic level in a time corresponding to the current value of the bias current, when the input signal reaches the one logic level, and lower the output voltage to a lower logic level, when the input signal reaches the other logic level.
