Abstract
Abstract There is disclosed a semiconductor integrated circuit device comprising: at least two first power supply voltage leads provided outside a chip adapted to be supplied with a first power supply voltage, e.g., VSS and a second power supply voltage, e.g., VCC and supplied with said first power supply voltage; at least two first power supply voltage terminals provided inside the chip, and connected to respective different ones of the first power supply voltage leads; an external input circuit adapted so that a signal is inputted from the outside of the chip, and connected to at least any one of first power supply voltage terminals; and an internal circuit adapted so that the signal is inputted from the external input circuit, and connected to one which is not connected to the external input circuit of the first power supply voltage terminals. Further, this semiconductor integrated circuit device may further comprise at least two second power supply voltage terminals provided inside the chip, and connected to respective different ones of the second power supply leads.
