Abstract:
A multi-bit level shifter that has a plurality of level shifters, each of which is configured to receive an input signal in a first voltage domain and provide a corresponding output signal in a second voltage domain. The level shifters each have an enable node. An enable circuit includes an output terminal connected to the enable node of each of the plurality of level shifters, and each of the plurality of level shifters is configured to output the corresponding output signals in response an enable signal received by the enable circuit.
