Abstract
Samples of the 54F109, 54AS109, 54ALS109, and the 54AHCT109, as well as, the 54F374, 54AS374, 54ALS374, and the 54AHCT374 were tested at the Berkeley Cyclotron. The results indicate that the 54AHCT109 possesses a LET threshold an order of magnitude greater and a SEU cross-section that is 20 times less than its advanced TTL counterparts. The same trend was shown for the 54AHCT374 where the LET threshold was 4 times greater than that for the 54F374 while the SEU crosssection was slightly less than that of the 54F374. These results indicate substantial improvement in SEU rejection by the 54AHCT family over advanced TTL.Keywords
