ABSTRACT:
An interconnection circuit having a circuit portion which is provided in one of two integrated semiconductors to be connected, for limiting the amplitude in voltage of the signal output from said one circuit, and another circuit portion which is provided in the other one of the two circuits, for discriminating the logic level of the signal input thereinto based on a threshold level set at an intermediate level between said amplitude. The amplitude of the logic signal transferred across the two circuits is thus compressed, thereby deereasing delay time for the signal to transfer between the two circuits.
