Abstract
A logic circuit made up of FET's is disclosed in which an output interface circuit is formed of a source follower circuit including a signal transmitting FET and a constant-current supplying FET, and a ratio of the gate width of the signal transmitting FET to the gate width of the constant-current supplying FET is set so that the high and low levels of the output signal of the logic circuit are independent of the threshold voltage of the FET's.
