Notes

4. The Voltage on any input or IO pin cannot exceed the power pin during power up.

7. See the last page of this specification for Group A subgroup testing information.

9. Input signals switch from 0 V to 3 V with a rise/fall time of less than 3 ns, clocks and clock enables switch at 20 MHz, while data inputs switch at 10 MHz. Outputs

are unloaded.

11. Tested initially and after any design changes that may affect these parameters.
