PROBLEM TO BE SOLVED: To provide an output driver circuit that improves quality of an output waveform.SOLUTION: The output driver circuit includes an on/off timing control circuit for outputting a first driving signal and a second driving signal such that, when output data is at a "Low" level, the second driving signal has a faster transition than the first driving signal in response to a transition of a signal based on the output data, and that when the output data is at a "High" level, the second driving signal has a slower transition than the first driving signal in response to a transition of the signal based on the output data. The output driver circuit includes a pull-down pre-driver and a pull-up pre-driver for outputting a pull-down signal and a pull-up signal in response to the first and second driving signals. The output driver circuit includes a pull-down main driver and a pull-up main driver for pulling down and pulling up a voltage of an output terminal in response to the pull-down signal and the pull-up signal. |
