Abstract:
A level shifter includes first and second input terminals, first and second output terminals, first pull-down circuitry operable to pull down one of the first and second output terminals responsive to signals present on the first and second input terminals, first pull-up circuitry operable to pull up the first output terminal responsive to a signal present on the second output terminal or pull up the second output terminal responsive to a signal present on the first output terminal, and second pull-up circuitry operable to pull up one of the first and second output terminals responsive to the signals present on the first and second input terminals.
