25. Cypress uses constant current (ATE) load configurations and forcing functions. This figure is for reference only. 5pF differential load reflects tester capacitance,
26. The LVTTL switching threshold is 1.4V. All timing references are made relative to the point where the signal edges crosses this threshold voltage.
27. Tested initially and after any design or process changes that may affect these parameters, but not 100% tested.
28. The ratio of rise time to falling time must not vary by greater than 2:1.
29. For a given operating frequency, neither rise or fall specification can be greater than 20% of the clock-cycle period or the data sheet maximum time.
