Absolute Maximum Ratings
Supply Voltage…………...…..…-0.3V ~ 5.5V
Input Voltage……… V
SS - 0.3V ~ VDD + 0.3V
Storage Temperature……………-50°C ~ 125°C
Operating Temperature…………..-25°C ~ 75°C
Note: These are stress ratings only. Stresses exceeding the range specified under “Absolute Maxi-
mum Ratings” may cause substantial damage to the device. Functional operation of this de-
vice at other conditions beyond those listed in the specification is not implied and prolonged
exposure to extreme conditions may affect device reliability.
