Abstract
PURPOSE: To use commonly a common terminal together with a normal input terminal without providing a private terminal in a test mode generation circuit by connecting the drain and the gate of the first FET to a power source voltage and the common terminal respectively and grounding the source and the gate of the second load FET.
CONSTITUTION: A common terminal is a terminal for normal input logic as well as test mode generation, and I2 is a normal input terminal, and normal input logic gates 11 and 12 are connected to these terminal respectively, and further, test mode generating circuit 13 is connected to the common terminal. Outputs of gate 11 and circuit 13 are inputted to NOR circuit 15, and outputs of gate 12 and circuit 13 are inputted to NOR circuit 16. In circuit 13, FETMT and load FETML are connected in series, and the drain of FETMT and the gate of FETMT are connected to power source voltage +VCC and the common terminal respectively, and the source and the gate of FETML are grounded. As a result, the common terminal can be used commonly together with the normal input terminal without providing a private terminal in circuit 13.
