So, whenever I see a "TBD" for anything important in a datasheet the warning bells are ringing. Kai, you take the specific (as in your examples above) and make it global. One TBD I often see is max Idd or Icc and those - not knowledge, but 'good guess' - will be related to transistor leakage. again - not knowledge, but 'good guess' - I would assume that particular value can vary quite a bit from fab to fab (e.g. precise enough litography vs much better lithography) without any adverse effect on the performance of the chip (except, of course, in battery powered apps). So Kai, while I agree with you where the TBD is a critical parameter, I see no reason to reject the use of a chip if the TBD is for a non-critical value. Erik |

| 120% agree!! | 01/01/70 00:00 | |

| Yes, guilty! | 01/01/70 00:00 | |

| Yes, live with the part, maybe, the vendor, never! | 01/01/70 00:00 | |
