PROTECTIVE CIRCUIT

摘要

PROBLEM TO BE SOLVED: To realize ESD protection between all the terminals mounted on an LSI. SOLUTION: In a protective circuit having an element for protecting the inner circuit of a semiconductor device against electrostatic discharge or electrical overstress, a bypass line 14 independent from the line of the inner circuit 15 is provided in the semiconductor device and protective elements 11-13 are connected between the bypass line 14 and the terminals 16-18 of the inner circuit 15, respectively.
