<p>An improved semiconductor integrated circuit having a circuit for monitoring an internal signal which is not taken out from a chip is disclosed.</p><p>The monitoring circuit includes a transistor having a control electrode to which the internal signal is applied, and a voltage switching element connected in series with the transistor between two external terminals. The voltage switching element is rendered conductive when a voltage of a predetermined value or more is impressed between the two external terminals.</p> |
