20.0 AC Characteristics at Vcc = 3.3V, TA=25° C (K=1.00)
The AC Specifications, Logic Cell diagrams and waveforms are provided below. To calculate delays,
multiply the appropriate K factor in the “Operating Range” section by the following numbers.

a. 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
specified in the Operating Range.
b. These limits are derived from a representative selection of the slowest paths through the Quick-
RAM logic cell including typical net delays. Worst case delay values for specific paths should be
determined from timing analysis of your particular design.
