Notes:

1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged exposure

to levels above the operating limits but below the Absolute Maximums may affect device reliability.

2. Typical values are at 25°C.

3. Not tested; guaranteed by design.
