Description
配線抵抗Rn、Rpは夫々出力回路の近傍の電源線GND、VDDと保護素子D0を接続する配線の寄生抵抗である。保護素子D0は各出力回路と共通に接続されるように配線される。図4から明らかなように、保護素子D0と各出力回路の近傍の電源線VDD又はGNDとを接続する配線は最短かつ均一になっている。その為、配線抵抗RpおよびRnの抵抗値は、出力回路のレイアウト位置によらず最小かつ均一の値にすることができる。
半導体装置8の各辺の近傍に外部と電気的接続をする入出力パッド3が設けられている。入力回路部7は、所定の入力パッド3から外部からの信号を受け所望の処理を実施する。出力回路部1、2は、所定の処理を受けた信号を受け、所定の出力パッド3に信号を出力する。
