a. Stated timing for worst case Propagation Delay over process variation at VCC = 2.5 V and
TA = 25 °C. Multiply by the appropriate Delay Factor, K, for speed grade, voltage and temperature
settings as specified in the operating range.
b. These limits are derived from a representative selection of the slowest paths through the logic cell
including typical net delays. Worst case delay values for specific paths should be determined from
timing analysis of your particular design.
