AC CHARACTERISTICS at VCC = 3.3V, TA = 25
°C (K = 1.00)
(To calculate delays, multiply the appropriate K factor in the "Operating Range" section by the following numbers.)

Input-Only/Clock Cells
Notes:
[5] Stated timing for worst case Propagation Delay over process variation at VCC=3.3V and TA=25
°C.
Multiply by the appropriate Delay Factor, K, for speed grade, voltage and temperature settings as speci-
fied in the Operating Range.
[6] These limits are derived from a representative selection of the slowest paths through the pASIC 3 logic
cell including typical net delays. Worst case delay values for specific paths should be determined from
timing analysis of your particular design.
