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 V
DD
ON, next V
EE
(V
4
), V
3
, V
2
, V
1
ON. Or both ON at the same time.
When turning power off:
First V
EE
(V
4
), V

OFF, next V
DD
OFF. Or both OFF at the same time.
