Notes:
1. Operation exceeds “Absolute Maximum Ratings” may cause permanent damage to the devices.
2. All voltages are referenced to V_SS.
• 3.3V ± 0.3V power supply for -5/-6/-6I speed grades.
• 2.7V~3.6V power supply for -7/-7I speed grades.
3. These parameters depend on the cycle rate and listed values are measured at a cycle rate with the minimum
values of t_CK and t_RC.
4. These parameters depend on the output loading conditions. Specified values are obtained with output open.
5. Power up sequence please refer to “Functional Description” section described before.
6. AC test load diagram.

7. t_HZ defines the time at which the outputs achieve the open circuit condition and is not referenced to output
level.
8. Assumed input rise and fall time (t_T) = 1nS.
If tr & tf is longer than 1nS, transient time compensation should be considered,
i.e., [(tr + tf)/2-1]nS should be added to the parameter
9. If clock rising time (t_T) is longer than 1nS, (t_T/2-0.5)nS should be added to the parameter.
