Figure 32. APEX 20K AC Test Conditions
Note to Figure 32:
(1)
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.
