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.
