Abstract:
An output driver configured to drive an output node includes a pull-down section having a plurality of legs and a pull-up section having a plurality of pull-up legs. Each leg and pull-up leg includes a data path and a calibration path. The data paths in the pull-down section are configured to conduct to ground responsive to an assertion of a complement data output signal whereas the data paths in the pull-up section are configured to conduct to a power supply node responsive to a de-assertion of the complement data output signal.
