Abstract
An output terminal is connected to an application terminal of a power supply voltage via a pull-up resister and a backcurrent prevention diode. An output transistor is disposed between the output terminal and a ground. A capacitor is connected between the gate of the output transistor and the output terminal. A charge-discharge circuit charges or discharges the gate of the output transistor in accordance with an input signal, and thus turns on or off the output transistor, so as to generate an output signal corresponding to the input signal, at the output terminal. The charge-discharge circuit set a charge current and a discharge current of the gate of the output transistor as an adjustment target current, and changes the adjustment target current nonlinearly in accordance with the power supply voltage.
