An output pad circuit is provided that adjusts a driving output current size within the chip based on a control signal. Thus, the output pad circuit adjusts a driving output current size, without attaching an external buffer or exchanging the output pad circuit, when an external load size varies during a chip design. The output pad circuit includes a tri-state inverter having an output being a tri-state level when a control signal is low level, but operating as an inverter when the control signal is high level.
