Summary:An output driver circuit includes a control circuit and first and second transistor legs that are coupled to an output pad. Each of the first and second transistor legs includes a pull-up transistor and a pull-down transistor. The control circuit is coupled to the first and second transistor legs. The control circuit enables the first transistor leg to generate an output signal at the output pad and disables the second transistor leg during a first phase of a cycle. The control circuit enables the second transistor leg to generate the output signal at the output pad and disables the first transistor leg during a second phase of the cycle. The control circuit repeats the first and the second phases of the cycle.
