4. The voltage on any input or IO pin cannot exceed the power pin during power-up.
5. TA is the “instant on” case temperature.
6. See the last page of this specification for Group A subgroup testing information.
7. 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 maximum frequency 20 MHz, while data inputs switch at
8. All inputs = V
9. Tested initially and after any design or process changes that may affect these parameters.
