Absolute Maximum Ratings
Supply Voltage........................VSS-0.3V to 5.5V
Storage Temperature.................-50°Cto125°C
Input Voltage.................VSS-0.3V to VDD+0.3V
Operating Temperature ..............-25°Cto70°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 device
at other conditions beyond those listed in the specification is not implied and prolonged expo-
sure to extreme conditions may affect device reliability.
