DATA TRANSMISSION CIRCUIT, DATA RECEPTION CIRCUIT AND DATA TRANSMISSION/RECEPTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a data transmission circuit that can enhance a data transfer rate without increasing a bus width by using one signal line and sending a plurality of data at the same time, and to provide a data reception circuit and a data transmission reception system. SOLUTION: In this system, a transmission line is driven in at least four levels by connecting the data transmission circuit provided with four MOSs connected to different kinds of power potentials to the data reception circuit provided with at least three comparators that respectively performs comparison with different reference levels through the transmission line.
