Abstract
An output buffer circuit of the present invention includes a first circuit which inputs an input signal and produces a first signal by adjusting the slew rate of the input signal and a second circuit which inputs the first signal and produces a second signal by increasing the slew rate of the first signal until a predetermined time period elapses from when the state of the first signal changes. The output buffer circuit has a transistor which includes a control terminal which inputs the second signal and a terminal connected to a transfer path.
