ABSTRACT:
A semiconductor integrated circuit has an internal circuit to execute a predetermined circuit operation, an input node to which output from the internal circuit is provided, and an output buffer capable of changing its driving ability placed between the input node and a signal outputs pad of the semiconductor integrated circuit. The outfit buffer has transistors connected in parallel for driving an external circuit connected to the signal output pad according to the output from the internal circuit and switching circuits. Each switching circuit switches a signal to be provided to each transistor. The switching state of each switching circuit is set according to the load capacity of the external circuit.
