Operating
Conditions
Tables 15 through 18 provide information on absolute maximum ratings,
recommended operating conditions, DC operating conditions, and
capacitance for 2.5-V APEX 20K devices. Consult Altera for specifications
on 1.8-V APEX 20KE devices.

Device
Output
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 ow through the
parasitic inductance between the device
ground pin and the test system ground,
signicant reductions in observable noise
immunity can result.
