WARNING: Recommended operating conditions are normal operating ranges for the semiconductor
device. All the device's electrical characteristics are warranted when operated within
these ranges.
Always use semiconductor devices within the recommended operating conditions.
Operation outside these ranges may adversely affect reliability and could result in device
failure.
