An apparatus for testing integrated circuits is disclosed. The apparatus for testing integrated circuits comprises an integrated circuit and a tester. The integrated circuit undergoing testing receives an input signal, and outputs an output signal from a first output terminal or a second output terminal according to a first pulse width of the input signal, and outputs an error signal according to a difference between the first pulse width and a second pulse width. The tester outputs the input signal according to the output signal and the error signal.
