Unit
V
Exceeding any one or a combination of the Absolute Maximum Rating conditions may
cause permanent damage to the device. Extended application of Absolute Maximum
Rating conditions to the device may reduce device reliability. Specified typical perfor-
mance or functional operation of the device under Absolute Maximum Rating condi-
tions is not implied.

degradation) which is determined by the technology process reliability. Refer
to product qualification report for FIT (random) failure rate.
Operation of this device beyond any one of these limits may cause
permanent damage. For reliable continuous operation, the device voltage and
current must not exceed the maximum operating values specified in the table
below.
Bias Conditions should also satisfy the following expression:
