configurable SRAM bit and all logic functionality ensures 100% yield.
AC test measurements for FLEX 10K devices are made under conditions
equivalent to those shown in Figure 19. Multiple test patterns can be used
to configure devices during all stages of the production flow.
Figure 19. FLEX 10K AC Test Conditions
Power supply transients can affect AC
measurements. Simultaneous transitions of
multiple outputs should be avoided for
accurate measurement. Threshold tests must
not be performed under AC conditions.

transients normally occur as the device
outputs discharge the load capacitances.
When these transients flow through the
parasitic inductance between the device
ground pin and the test system ground,
significant reductions in observable noise
immunity can result. Numbers without
parentheses are for 5.0-V devices or outputs.
Numbers in parentheses are for 3.3-V devices
or outputs. Numbers in brackets are for
2.5-V devices or outputs.
