Claims (2)
- 端子から電源電圧線の電圧よりも高電圧の信号を印加できる入出力回路を有する半導体装置であって、前記端子と基準電位線との間にアノードを基準電位線側にして第1のダイオードを接続するとともに、前記端子と電源電圧線との間に抵抗を介してベースをエミッタに接続しコレクタを前記端子側にしたNPN型のトランジスタとカソードを電源電圧線側にした第2のダイオードとを直列接続した保護回路を有し、前記トランジスタのパンチスルー電圧を越える電圧が前記端子に印加されたときに前記トランジスタを介して該電圧による電流を電源電圧線に流せるようにし、前記入出力回路に印加される電圧を低下するようにしたことを特徴とする半導体装置。
- 前記保護回路を介して流れる電流による電源線の電圧変動を抑えるための電源間保護回路を前記端子近傍の基準電位線と電源電圧線との間に設けたことを特徴とする請求項1に記載の半導体装置。
