Abstract
There are provided: a first logic operation circuit which performs a logic operation using a high-amplitude logic signal; a transmission system having a load capacitance; and a low-voltage signal generator which is a step-down level shifter transforming an incoming high-amplitude logic signal from the first logic operation circuit to a low-amplitude logic signal having a lower amplitude than the high-amplitude logic signal for output to the transmission system. In the configuration, the first logic operation circuit operates based on a high-amplitude logic signal, and is therefore free from malfunctions and performs operations at high speed. Further, the transmission system introducing a load capacitance transmits a low-amplitude logic signal and therefore restrains increases in electric power consumption and occurrence of unnecessary radiation.
