Abstract
To include an output terminal, unit buffers, and plural output-wiring paths that respectively connect the unit buffers and the output terminal. The output wiring paths have individual output wiring sections individually allocated to corresponding unit buffers. Unit buffers corresponding to these output wiring paths are common output wiring sections shared by the output wiring paths, and are connected to the output terminal without via a common output wiring section having a higher resistance value than those of the individual output wiring sections. Accordingly, an deviation of impedance due to a parasitic resistance between the output terminal and the unit buffers is suppressed.
