AC TEST CONDITIONS
The AC specifications are tested with the 50 pF load
shown in Figure 7. See the Derating Curves section
to see how timings vary with load capacitance.
Specifications are measured at the V
CC
/2 crossing
point, unless otherwise specified. See AC Timing
Waveforms for AC specification definitions, test pins
and illustrations.
