入力回路。[Claims for Utility Model Registration] A regular circuit section that operates upon input of a drive signal and outputs a regular signal after a predetermined time; an output section that outputs a predetermined signal upon input of the regular signal; and a regular circuit section that outputs a prescribed signal upon input of the regular signal; In the test signal input circuit of the ASIC, the ASIC includes a test circuit section that operates and outputs the same signal as the regular signal to the output section within the predetermined time, and inputs the test signal to the test circuit section. A test signal input circuit for an ASIC, comprising signal generating means for generating and outputting the test signal in the test circuit section by inputting a logic signal that does not cause the normal circuit section to operate to an external input terminal of the ASIC.
