Abstract
Various exemplary aspects of the present invention provide methods and apparatus for powering down the line driver to a state that reduces power dissipation without affecting the overall impedance of the line driver. More particularly, a power down state for line drivers and the like is suitably provided that saves power when no transmission is required. The power down mode suitably provides line termination for received data. According to various aspects of an exemplary embodiment, output devices are configured at power down such that a low impedance is maintained.
