PURPOSE:To extend the noise margin of device itself by supplying a control- signal input circuit with a stable power supply while forming a power supply to an internal logic circuit section in another system by directly feeding the power supply to the control-signal input circuit through a power line. CONSTITUTION:Power lines 8, 9 fed to a control-signal input circuit 3 are connected to a VCC terminal 6 and a GND terminal 7 in shortest size while control terminals and input protective circuit 10 are arranged brought near to these VCC terminal 6 and GND terminal 7, and a line after supply to the control-signal input circuit 3 is used or another system line is employed regarding a power supply to an internal logic circuit section 1. The control-signal input circuit can be supplied with the further stable power supply while resistance to noises can be increased. |
