NOTICE

Absolute maximum ratings are the extreme limits that the device will withstand without

damage to the device. However, the electrical and mechanical characteristics are not

guaranteed as the maximum limits (above recommended operating conditions) are

approached, nor will the device necessarily operate at absolute maximum ratings.
