    Abstract: PROBLEM TO BE SOLVED: To provide an electrostatic discharge(ESD) protective network, which has such structural and functional features that meet the nonsensitive requirements of a substrate for noise and accordingly, can isolate various circuit blocks from noise or disturbance. SOLUTION: An ESD protective network incorporates first ESD protective parts 14 for the input stage of a circuit structure, second ESD protective parts 5 for the output stage of the circuit structure, at least one ESD protective parts B0 between a primary power source Vcc and a primary ground GND, and at least one EDGE protective parts B between a secondary power source Vcc- IO and a secondary ground GND- IO, and the first and second protective parts 15 and 5 commonly use the input-output terminal 20 of an integrated circuit structure.
