SEMICONDUCTOR INTEGRATED CIRCUIT INCLUDING AN INTERNAL CIRCUIT AND AN ELECTROSTATIC PROTECTION CIRCUIT CAPABLE OF REDUCING THE NUMBER OF ELECTROSTATIC PROTECTION DEVICES

摘要

PURPOSE: A semiconductor integrated circuit including an internal circuit and an electrostatic protection circuit is provided to reduce the number of electrostatic protection circuits by increasing the separation part of a power voltage and a ground voltage.;CONSTITUTION: A semiconductor integrated circuit includes first to third operation voltage supply terminals, first to third internal circuits(11,12,13), first to third electrostatic protection circuits(41,42,43), and a connection center trap. The first to third internal circuits are operated with first to third operation voltages of the first to third operation voltage supply terminals. First to third electrostatic protection circuits are connected between the first to third operation voltage supply terminals and the connection center trap.;COPYRIGHT KIPO 2012
