Abstract
An interface circuit includes a signal sending section having a first MOS transistor and a second MOS transistor which are alternately turned ON in accordance with a binary input signal. A signal receiving section has a third MOS transistor connected through a first signal transmission path to the first MOS transistor mounted in the signal sending section to feed a current with a predetermined value through the first signal transmission path when the first MOS transistor mounted in the signal sending section is turned ON. A fourth MOS transistor connected through a second signal transmission path to the second MOS transistor mounted in the signal sending section feeds a current with a predetermined value to the second signal transmission path when the second MOS transistor mounted in the signal sending section is turned ON.
