摘要： The objective of this invention is to provide a test device that can perform a variety of function tests with a relatively simple constitution. The test device is for testing semiconductor device 1, which contains input terminal IN, output terminal OUT and control terminal CTRL, and whose output terminal is in the high-impedance state corresponding to the control signal applied to control terminal CTRL. The test device comprises test signal supply circuit 20, comparator 30 that compares the output signal from the output terminal with a reference voltage, reference voltage setting part 40 that sets the reference voltage to the voltage on the high-level side or on the low-level side, and load voltage supply circuit 50 that applies the load voltage to the output signal when the control signal is input. Said load voltage supply circuit 50 applies a load voltage greater than the voltage on the high-level side when the reference voltage is set to the high-level side, and it applies a load voltage less than the voltage on the low-level side when the reference voltage is set to the low-level side.
