ABSTRACT:
A low power method and apparatus for selecting operational modes of a circuit. One circuit according to the teachings of the disclosed method and apparatus includes a first current limiting circuit coupled between a selector terminal and a first voltage bus. The first current limiting circuit is adapted to vary a current limit out of the selector terminal in response to a voltage on the selector terminal. The circuit also includes a second current limiting circuit coupled between the selector terminal and a second voltage bus. The second current limiting circuit adapted to vary a current limit into the selector terminal in response to the voltage on the selector terminal.
