Notes:

1. Operation exceeds âAbsolute Maximum Ratingsâ may cause permanent damage to the devices.

2. All voltages are referenced to VSS.

3. These parameters depend on the cycle rate and listed values are measured at a cycle rate with the

minimum values of tCK and tRC.

4. These parameters depend on the output loading conditions. Specified values are obtained with

output open.

5. Power up sequence please refer to âFunctional Descriptionâ section described before.

6. AC test load diagram.

7. tHZ 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 (tT) = 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 (tT) is longer than 1nS, (tT/2-0.5)nS should be added to the parameter.
