Abstract
When a low supply potential has risen while a high supply potential has not risen, a logical value '0' is output as an output signal by applying a ground potential to an input terminal of a latch circuit through a capacitor. On the other hand, when the high supply potential has risen while the low supply potential has not risen, a logical value '0' is output as an output signal by converting the high supply potential into the ground potential by the level shifter. If both the low supply potential and the high supply potential have risen, the logical value “1” is output as an output signal by converting the ground potential into the high supply potential by the level shifter.
