Derating Timing Tables
Logic timing provided in the following sections of this data sheet and the ispLEVER design tools are worst case
numbers in the operating range. Actual delays at nominal temperature and voltage for best case process, can be
much better than the values given in the tables. The ispLEVER design tool can provide logic timing numbers at a
particular temperature and voltage.
