Absolute Maximum Ratings
Supply voltage.......................... 0V to 2.0V
Input voltage............. VSS–0.5V to VDD+0.5V
Operation Temperature......... –20°C to +75°C
Storage Temperature.......... –55°C to +125°C
*Note: Stress above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. These are stress ratings only. Functional operation of this device at these or any other conditions
above those indicated in the operational sections of this
specification is not implied and exposure to absolute maximum rating conditions for extended periods may
affect device reliability.
