摘要:
A method and apparatus for translating signals between different components located in different power boundaries in a mixed voltage system. A level shifter system includes a first level shifter circuit connected to a first voltage source. A second level shifter circuit connects to a second voltage source. An intermediate level shifter circuit has an input that connects to the output of the first level shifter circuit. The output of the intermediate level shifter circuit connects to the input of the second level shifter circuit. The intermediate level shifter circuit uses an intermediate voltage source having an intermediate voltage about midway between the first voltage of the first voltage source and the second voltage of the second voltage source.
