OUTPUT DRIVER WITH BACK-POWERING PREVENTION

摘要

A back-power prevention circuit (205) is provided that protects a buffer transistor (MPl) from back-power during a back-power condition by charging a signal lead (PCLT) coupled to a gate of the buffer transistor (MPl), to a pad voltage (PadSig) and by charging a body (235) of the buffer transistor (MPl) to the pad voltage (PadSig, NW).
