    摘要: Various apparatuses, methods and systems for protecting a driver from electrostatic discharge are disclosed herein. For example, some exemplary embodiments provide a driver, including a buffer, a leakage path blocking transistor connected to an output of the buffer, and an output driver connected to an output of the leakage path blocking transistor. Current from the output driver to the buffer is substantially blocked by the leakage path blocking transistor.

    摘要: An apparatus for reducing current leakage between an input locus and at least one power rail for a system includes, for each respective power rail: (a) A first diode unit coupled between the input locus and a coupling locus. The first diode unit is configured to effect substantially zero potential drop during normal operation of the apparatus. (b) A second diode unit coupled between the coupling locus and the respective power rail. The second diode unit is configured to present no forward bias during normal operation of the apparatus. The first and second diode units cooperate to effect current flow between the input locus and the respective power rail during a predetermined operational condition of the apparatus.
