Note 1
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.
Note 2
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Note 3
When connecting a bias resistor externally, set the LCD power supply voltage so that the state is
changed to VSS
