Note 1: Stress beyond the maximum ratings listed above may incur permanent damage to the device. Operating above the

recommended conditions for extended time may stress the device and affect device reliability. Also the device may not operate

normally above the recommended operating conditions. These are stress ratings only.

Note 2: Guaranteed by design; not test in production.
