A Zero “0” Hold Time listing indicates no hold ti
listed, there is no positive hold time.
These items are of interest for Carry Chain applications.
A Zero “0” Hold Time listing indicates no hold time or a negative hold time. Negative values cannot be guaranteed “best-case”, but if a “0” is
listed, there is no positive hold time.
