Abstract

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.
