MULTI POWER SUPPLY TYPE LEVEL SHIFTER

摘要

The present invention relates to a multi-power supply type level shifter. The multi-power supply type level shifter equips a first level shifter and a second level shifter in two stages to change a signal level by receiving first to third powers selectively. Even if the first to third powers are applied differently from a general power application sequence, the level of an output voltage is not changed and outputted not to generate a short circuit current from the first and second level shifts.
