NOTES ON USE
Note the following when turning power on and off:
The LCD drivers of this IC require a high voltage. For this reason, if a high voltage is applied to
the LCD drivers with the logic power supply floating, excess current flows. This may damage
the IC. Be sure to carry out the following power-on and power-off sequences:
When turning power on:
First VDD ON, next VEE (V4), V3, V2, V1 ON. Or both ON at the same time.
When turning power off:
First VEE (V4), V3, V2, V1 OFF, next VDD OFF. Or both OFF at the same time.
