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.

‡
The core supply should be powered up prior to (and powered down after), the I/O supply. Systems should be designed to ensure that neither
supply is powered up for an extended period of time if the other supply is below the proper operating voltage.
§
These values are compatible with existing 1.26−V designs.
¶
Refers to DC (or steady state) currents only, actual switching currents are higher. For more details, see the device-specific IBIS models.
#
The absolute maximum ratings should not be exceeded for more than 30% of the cycle period.
