Note
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a
stress rating only and the functional operation of the device at these or any other conditions above those indicated in the
operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.

Drastic fluctuation by power supply voltage, input signal voltage noise, etc. causes malfunction and normal operation
can not be guaranteed. In any case, avoid intentionally changing the power supply voltage during operation.

,
COM
to
COM
) and
the LCD drive power pins (V

pins). R
ON
is measured between the LCD drive power pins and the LCD
drive output pins whose electric potential is the same as that of the LCD drive power pins.
