IPC: H03K17/687
Filed: 2000-12-06
Abstract: PROBLEM TO BE SOLVED: To provide a level shifter circuit which can perform a high speed operation and in which a consumption current is small when a power supply voltage of a low potential is a very low voltage and when the voltage difference between a power supply voltage of a high potential and the power supply voltage of the low potential is large.
