AC CHARACTERISTICS at VCC = 5V, TA = 25 C (K = 1.00)
Propagation delays depend on routing, fanout, load capacitance, supply voltage, junction temperature,
and process variation. The AC Characteristics are a design guide to provide initial timing estimates at
nominal conditions. Worst case estimates are obtained when nominal propagation delays are multiplied
by the appropriate Delay Factor, K, as specified in the Delay Factor table (Operating Range). The
QuickChip/QuickTools/QuickWorks software incorporates data sheet AC Characteristics into the
design database for precise path analysis or simulation results following place and route.

Stated timing for worst case Propagation Delay over process variation at VCC=5.0V and TA=25 C.
These limits are derived from a representative selection of the slowest paths through the pASIC 2 logic
Multiply by the appropriate Delay Factor, K, for speed grade, voltage and temperature settings as
specified in the Operating Range.
