Note 4:
Absolute maximum ratings are those values beyond which the de-
vice may be damaged or have its useful life impaired. Functional operation
under these conditions is not implied.
Note 5:
ESD testing conforms to MIL-STD-883, Method 3015.
Note 6:
Either voltage limit or current limit is sufficient to protect inputs.

Note 7:
F100K 300 Series cold temperature testing is performed by temperature soaking (to guarantee junction temperature equals −55˚C), then testing immediately
without allowing for the junction temperature to stabilize due to heat dissipation after power-up. This provides “cold start” specs which can be considered a worst case
condition at cold temperatures.
Note 8:
Screen tested 100% on each device at −55˚C, +25˚C, and +125˚C, Subgroups, 1, 2 3, 7, and 8.
Note 9:
Sample tested (Method 5005, Table I) on each manufactured lot at −55˚C, +25˚C, and +125˚C, Subgroups A1, 2, 3, 7, and 8.
Note 10:
