There were no functional failures at any irradiation level. All parametric measurements remained well within data sheet (SBOSA52A) limits and within the production test limits, which are guard-banded from the data sheet limits for all exposure levels. The full parameter list and graphs are found in Appendix A. In the graphs, Delta and Delta % refer to the deviation due to radiation exposure.

Delta = Pre NDD - Post NDD

Delta % = Delta / Pre NDD

% of Limit Range = ABS (Delta) / ABS (Max Limit - Min Limit)

The Fail Limit range is a guard-banded limit that Texas Instruments puts into test programs to insure device performance. It is always set within the data sheet limits to insure the device meets all data sheet parameters. In case of some parameters, the % of Limit Range is showing high due to tight test limit range, but the maximum Delta % is about 5%. Texas Instruments has collected more parameters than what is shown in this report for characterization purposes.
