Abstract

PURPOSE:To prevent the malfunction at a power supply time, by supplying an inject current to the base of the output-stage transistor of an interface circuit consisting of an IIL through a diode. CONSTITUTION:At the rise time of a power source 13 for power supply, when the potential of an output A becomes about 1VBE and the potential of an output B becomes 1VBE or below after a slight delay, there is probability that a gate circuit 14 is turned on. In this case through a transistor 15 of an interface circuit 12 is turned off, a transistor 16 continues turned off because the output A is applied to the base of the transistor 16 through a resistance 18 and a diode 21. When the potential of the output A becomes 2VBE and the potential of the output B becomes 1VBE, the operation becomes normal.
