3.  Absolute Maximum Ratings

 VSS=0V, Ta=25ºC
Item Symbol Min. Max. Unit
Supply Voltage 3.3V_VCC -0.3 6.0 V
3.3V_VCI -0.3 6.0  
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.
