An interface for translating data of different voltages includes an input terminal structured to accept an input from a circuit supplied by a power supply having a first voltage level, as well as an output terminal structured to provide an output from the interface a first circuit portion powered by a power supply having the first voltage level, a second circuit portion is powered by a power supply having a second voltage level, and a power supply detection circuit structured to accept a detection signal and to maintain a correct output at the output terminal even after the power supply having the first voltage level no longer supplies the first voltage level to the interface.
