Low power single port level shifter using a power down signal from an output power range and a method of converting a data signal between power ranges

摘要

This provides a voltage level shifter, a device with a voltage level shifter, and a method for converting voltages between an input power range and an output power range. In one embodiment, the voltage level shifter comprises: (1) an input circuit configured to receive a data signal from an input power range and a power shutdown signal from an output power range, and (2) a transition circuit connected and configured to the input circuit, the data signal and receive an inverted signal of the power cut-off signal, wherein the input circuit and the transition circuit are each designed to be connected to a supply voltage of the output power range as a power source.
