Electrical Characteristics Notes
1. All voltage values are referred to GND = 0V. If the LSI is used above the absolute maximum ratings, it
may become permanently damaged. Using the LSI within the given electrical characteristic is strongly
recommended to ensure normal operation. If these electrical characteristic are exceeded, the LSI may
malfunction or exhibit poor reliability.
