† 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:

1. All voltage values, except differential I/O bus voltages, are with respect to GND, and are steady-state (unless otherwise specified).

2. Tested in accordance with JEDEC Standard 22, Test Method A114-A.

3. Tested in accordance with JEDEC Standard 22, Test Method C101.
