Filed: 2001-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a level shift circuit in which a fast operation is performed without pulling up a node with a small latch and a layout area is small. SOLUTION: In this level shift circuit provided with a latch composed of two P type transistors, when the input signal of a terminal IN is changed, e.g. from an H level to an L level, a P type transistor P4 is off and a through- current made to flow from high voltage sources VDDs3 to the ground through a transistor P2 and an N type transistor N2 is interrupted even though the transistor N2 is turned on to lower the potential of a node W2. Meanwhile, even though an N type transistor N1 is turned off and a P type transistor P3 is also turned off to interrupt both ends of a node W1, the sources VDDs3 pulls up a node W1 through the transistor P4, a resistance P5 and a P type transistor P1. Then, the driving capacities of the transistors N1 and N2 are made small and delay time is shortened.
