Abstract

PURPOSE:To obtain an adequate fault-output preventing function, by composing a logical element for output control and another logical element for cutting-off operation by using the same digital logical element. CONSTITUTION:A control circuit 1 which includes a logical element 4 for output control, an output cutting-off circuit 2, and a load circuit 3 to be controlled are provided, and the output signal of the control circuit 1 is inputted to the load circuit 3 to be controlled through the output cutting-off circuit 2. A cutting-off logical element 5 is composed of the same digital logical element with the element 2, and the output cutting-off circuit 2 is controlled by its output. Therefore, the load circuit 3 to be controlled never malfunctions.
