  • Multiple function power domain level shifter
    Patent number: 8339177
    Abstract: A level shifter including input and output power nodes, input and output reference nodes, input and output signal nodes, and a lever shifter network. The input power and input reference nodes operate within a first power domain and the output power and output reference nodes operate within a second power domain. The level shifter network receives an input signal operable within the first power domain, performs voltage shifting between the input and output power nodes and between the input and output reference nodes, and provides an output signal output signal indicative of the input signal that operates within the second power domain. The level shifter may include power and/or ground bypass such that either one or both of power and ground voltage shifting may be bypassed for faster switching. The level shifter may include an isolation input to assert the output to a known level.
