Figures 1, 2
Note 7:
F100K 300 Series cold temperature testing is performed by temperature soaking (to guarantee junction temperature equals −55˚C), then testing immediately
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 +25˚C temperature only, Subgroup A9.
Note 9:
Sample tested (Method 5005, Table I) on each manufactured lot at +25˚C, Subgroup A9, and at +125˚C and −55˚C temperatures, Subgroups A10 and A11.
Note 10:
Not tested at +25˚C, +125˚C, and −55˚C temperature (design characterization data).
Note 11:
The propagation delay specified is for single output switching. Delays may vary up to 300 ps with multiple outputs switching.
