Absolute Maximum Ratings
(Note 5)
Recommended Operating
Conditions
Note 5:
The
Absolute Maximum Ratings
are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The
Recommended Operating Conditions
table will define the conditions
for actual device operation.
Note 6:
The specified limits represent the
worst case
value for the param-
eter. Since these values normally occur at the temperature extremes, addi-
tional noise immunity and guardbanding can be achieved by decreasing the
allowable system operating ranges. Conditions for testing shown in the
tables are chosen to guarantee operation under
worst case
conditions.
Note 7:
ESD testing conforms to MIL-STD-883, Method 3015.
