3. Absolute Maximum Ratings
V_SS=0V, Ta=25ºC

Item	Symbol	Min.	Max.	Unit
Supply Voltage	VDD	-0.3	4.8	V
Supply Voltage(Logic)	VDDIO	-0.3	4.8	V
Storage temperature	Tstg	-30	+80	ºC
Operating temperature	Top	-20	+70	ºC

Note 1: If Ta below 50ºC, the maximal humidity is 90%RH, if Ta over 50ºC, absolute humidity should be less than 60%RH.
Note 2: The response time will be extremely slow when the operating temperature is around -10℃, and the back ground will become darker at high temperature operating.
