• a first switch circuit, electrically connected to the control circuit, to control the first switch circuit according to the output signal;
• a second switch circuit, electrically connected to the control circuit, to control the second switch circuit according to the output signal;
• a first inverter, having a first input end and a first output end, and electrically connected between the voltage feed end and a second input end, wherein the first input end is electrically connected to the first switch circuit;
• a second inverter, having the second input end and a second output end, and electrically connected between the first output end and a ground end, wherein the second input end is electrically connected to the second switch circuit;
• and
• a discharge circuit, electrically connected between the voltage feed end and the ground end, and controlled by the first output end and the second output end, wherein
• when static electricity is inputted into the signal input end, the output signal transitions to a high-voltage level, the discharge circuit is turned on through the first switch circuit and the second switch circuit to discharge the signal input end, and the trigger signal generated by the first node through the trigger circuit transitions to a low-voltage level, to control the control circuit to extend output time in which the output signal stays at the high-voltage level.
