<p>Provided is a semiconductor integrated circuit device having an output portion that outputs via a switch element a predetermined voltage to the outside from a voltage output terminal through a voltage output line and a control portion that performs predetermined control based on a control signal inputted from outside to a signal input line or a signal input terminal that is so arranged as to be adjacent to a voltage output line or a voltage output terminal. To achieve a highly-reliable semiconductor integrated circuit device that is prevented from being broken even when the voltage output terminal and a terminal adjacent thereto are short-circuited, there is provided a voltage detection portion that detects that a voltage higher than a reference voltage is inputted to the signal input line or the signal input terminal and feeds the resultant signal to the output portion as a voltage detection signal, and the output portion opens the switch element when the voltage detection signal is provided thereto.</p> |
