Abstract

PURPOSE:To simplify a reliability test corresponding to an operating state by outputting a predetermined oscillation output signal to an oscillation output line in response to ON/OFF of a specific power source electrically insulated from a power source to be supplied to an OR circuit. CONSTITUTION:Input signals from input terminals 52-1-52-m are input to one input sides of OR circuits 1-1-1-m. The oscillation output signal of an oscillator 2 is input to the other input sides of the circuits 1-1-1-m. When a predetermined power is supplied through an input terminal 53 to the oscillator 2, the oscillation output signal of the oscillator 2 is transmitted to the circuits 1-1-1-m. When no input signal is output from the terminals 52-1-52-m, it is input through the circuits 1-1-1-m to an internal circuit 3 as it is. Then, the circuit 3 can be operated without inputting the input signal to the terminals 52-1-52-m. Thus, a reliability test corresponding to the operating state is simplified.
