NOTES ON USE (when turning the power ON or 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 follow the sequence below when turning the power ON or OFF.

Power ON : Logic circuits ON Æ LCD drivers ON, or both ON at a time

Power OFF : LCD drivers OFF Æ logic circuits OFF, or both OFF at a time
