<p>An output circuit outputs data from an output terminal Dout after the potential at the terminal Dout is set at a prescribed intermediate value between the potential at the power source line and that at the ground line. The output circuit is provided with an output driving means (30) composed of first and second transistors (31 and 32). The first transistor (31) is provided with a first control terminal DP to which a first control signal is inputted and the second transistor (32) is provided with a second control terminal DN to which a second control signal is inputted. The output circuit is also provided with a setting means (22) which turns the transistors (31 and 32) off by controlling the first and second control signals and a short-circuiting means (50) which short-circuits either of the control terminals DP and DN to the output terminal Dout. Before the data are outputted, after the transistors (31 and 32) are turned off by the setting means (22), the potential of the output terminal Dout is set at the intermediate value by short-circuiting the control terminal DP or DN to the output terminal Dout by means of the short-circuiting means (50).</p> |
