Patent ID: 6888444

Claim:
A signal transmitting/receiving circuit comprising: a differential-signal generating portion for expressing a signal to be transmitted as a pair of differential signals having potentials shifting in opposite directions, the potential of one of said differential signals being a potential at a power source of a signal receiving circuit; a pair of lines for differentially transmitting the differential signals generated from said differential-signal generating portion; and a signal receiving circuit composed of a transistor; wherein said signal receiving circuit receives the differential signals transmitted by said pair of lines, and respective potentials at at least two of a source electrode, a gate electrode, and a substrate electrode of said transistor change in synchronization with the change of the differential signals; said transistor is turned ON when the potential of one of the differential signals rises and the potential of the other of the differential signal falls; and said transistor is turned OFF when the potential of the other of the differential-signals rises and the potential of one of the differential signals falls.
