Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
4. Unless otherwise noted, all voltage values are with respect to VSS1.
5. Electrical characteristics are specified with all output buffers loaded with specified IO current. Exceeding the specified IO current in
any buffer can affect the levels on other buffers.
