Approximate internal connection circuits
Absolute Maximum Ratings
Supply Voltage...............................-0.3V to 13V
Input Voltage ...................VSS-0.3 to VDD+0.3V
Storage Temperature.................-50°Cto125°C
Operating Temperature ..............-20°Cto75°C
Note: These are stress ratings only. Stresses exceeding the range specified under ²Absolute Maxi-
mum Ratings² 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.
