The Notes on Use

Important things for stability operation of IC are shown as follows. The contents indicated below do not guarantee IC

operation and the characteristic. Moreover, the example of an application circuit written in these specifications is for

explaining internal operation and usage. Therefore, please perform the design in consideration of the specification of

operation and terms and conditions in the actual LCD panel.

(1) The design of power supply

All power supply pads are connected to the power supply, and do not set open.

(2) ITO (Indium Tin Oxide) wiring

By designing the wire of power supply (VDD, VDDI, VSS) wide and short, make the parasitic resistance of ITO

wiring into the minimum.

(3) Signal wiring and connection

The DUMMY pad does not connect to anywhere, and sets open.

(4) Processing of unused input pad

For CMOS process, if an input pad is in open state, operation of IC may become unstable, or unnecessary power

supply current may flow through it. Please be sure to connect the empty pad of a logic input to VSS.

(5) The measure against shading

The optical irradiation to IC causes the mis-operation of IC. When IC is implemented, take the measures against

shading about the surface, back and side of IC.
