Abstract
In a level shift circuit allows satisfactory operation with short delay time in the case of low-voltage setting of a low-voltage source, for example, when a state of an input signal IN transitions from a H (VDD) level to a L level, a node Wprecharged to a H (VDD) level is discharged to ground (VSS) by a discharge circuit N, and decreases in potential. The decrease in potential propagates to a latch circuit LA, and an output of the latch circuit LA propagates to an output circuit OC. Further, an inversion signal of the node Wis input to the output circuit OC by bypassing the latch circuit LA. Thus, the output circuit OC starts operating prior to operation based on an output of the latch circuit LA.
