Generic Testing

Each FLEX 10K device is functionally tested. Complete testing of each

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.

Conditions

Tables 17 through 21 provide information on absolute maximum ratings,

recommended operating conditions, DC operating conditions, and

capacitance for 5.0-V FLEX 10K devices.

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.

Large-amplitude, fast-ground-current

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.
