Abstract
A semiconductor integrated circuit device is provided with an internal circuit which receives a source voltage supplied from an external terminal and is activated based on a voltage obtained by reducing the source voltage, and an output circuit which outputs a signal to be outputted produced by the internal circuit, through an external terminal in accordance with a timing signal. In the semiconductor integrated circuit device, a level shift circuit converts the signal produced by the internal circuit to a signal level corresponding to the level of the source voltage supplied from the external terminal. The output circuit outputs the level-shifted signal therefrom using a timing signal of a voltage level corresponding to the source voltage supplied from the external terminal.
