6.2 Recommend Operation Conditions
Operating ranges define the limits for functional operation and parametric characteristics of the device. Note that the functionality of the
chip outside these operating ranges is not guaranteed. Operating outside the recommended operating ranges for extended periods of
time may affect device reliability.
