ABSTRACT:
A different power sources interface circuit for connecting a first power source operating circuit for supplying complementary outputs with a second power source operating circuit having a power source for supplying a voltage higher than that of the power source of the first power source circuit comprises an input transistor circuit including first and second N channel MOS transistors which are in series connected between said second power source and a ground and have respective gates to which the complementary outputs of said first power circuit are supplied; a first inverter circuit having an input connected with a connection between both said transistors; and a second inverter circuit having an input and an output thereof which are connected with the output and input of said first inverter circuit, respectively.
