Absolute Maximum Ratings are limiting values to be applied individually and
beyond which the serviceability of the circuit may be impaired. Functional
operability under any of these conditions is not necessarily implied. Exposure to
absolute maximum rating conditions for extended periods of time may affect
device reliability.
EXPLANATION OF TEST LEVELS
I.
Devices are 100% production tested at 25
°
C and guaranteed
by design and characterization testing for the commercial
operating temperature range (–40
°
C to +85
°
C).
II. Parameter is guaranteed by design and/or characterization
testing.
III. Parameter is a typical value only.
