LEVEL SHIFTER AND SEMICONDUCTOR DEVICE HAVING OFF-CHIP DRIVER |
摘要 |
Provided are a level shifter and a semiconductor device having an OFF-chip driver (OCD) using the same. The level shifter includes a plurality of series connected logic gates receiving a first-state input signal having a first power supply voltage level and generating a level-shifted first-state output signal having a second power supply voltage level. The logic gates receive as power supply voltages at least one intermediate power supply voltage having at least one voltage level intermediate between the first power supply voltage level and the second power supply voltage level, and an intermediate power supply voltage applied to the present logic gate is equal to or higher than an intermediate power supply voltage applied to the previous logic gate.
