Abstract
PURPOSE:To control an output current only by connecting a simple gate circuit by providing a transistor gate circuit for an output current control at the output part of an output buffer circuit integrated in a semiconductor substrate, and controlling the input signal of a gate circuit. CONSTITUTION:The output of an output buffer circuit 1 is outputted from an output terminal 9 through a transistor 6 of a gate circuit 5. By changing the size of a voltage impressed to a control signal terminal 7, the ON resistance of the transistor 6 can be changed. For that reason, the size of the output current of the output buffer circuit 1 can be controlled. In short, when the ON resistance of the transistor 6 is minimized, an large output current is obtained and when the ON resistance is enlarged, a small output current can be obtained.
