ABSTRACT:
Inter-circuit interference such as a switching noise is suppressed without deteriorating the circuit integration. An output buffer (1) is connected to power source lines (11) and (21) by though holes. In a similar manner, an output buffer (2) is connected to power source lines (11) and (21) and an output buffer (3) is connected to power source lines (22) and (12). The power source lines (21) and (22) are disposed on the same straight line and terminate in an area which is sandwiched by the output buffers (2) and (3). The power source lines (11) and (12) are disposed on the same straight line and terminate in an area which is sandwiched by the output buffers (2) and (3). The power source line for supplying electric power to the output buffers (1) and (2) and the power source line for supplying electric power to the output buffer (3) are separated from each other, and therefore, inter-circuit interference such as a switching noise will not be created between the output buffers (1), (2) and the output buffer (3).
