Abstract

PURPOSE: To reduce the number of terminal pins in case of the IC-implementation of the transmission side and reception side with the number of transmission lines reduced by transmitting a clock pulse signal and data signal through an earth line and another transmission line.
CONSTITUTION: Between operational power supply +Vc and reference potential "O", the 1st resistance element R1 and the 1st switching element SW1 are connected sequentially in series, and between center connection point l between resistance element R1 and switching element SW1 and reference potential "O", the series circuit of the 2nd resistance R2 and the 2nd switching element SW2 are connected. Then, switching element SW1 is driven by a clock signal, and switching element SW2 is by a data signal so as to extract the clock signal and data signal from center connection point l, thereby transmitting the clock signal and data signal through the earth line and another transmission line. The 1st and 2nd switching elements SW1 and SW2 in this constitution employ MOS transistors, respective drains are connected to resistance elements, and gates are applied with signals respectively
