Notes:
2. The V_IH and V_IL specifications apply for all inputs except XI. The XI pin is not a TTL input. It is connected to either XO of the previous device or V_SS.
3. Test no more than one output at a time for not more than one second.
4. Input signals switch from 0V to 3V with a rise/fall time of less than 3 ns, clocks and clock enables switch at maximum frequency (f_MAX), while data inputs
switch at f_MAX/2. Outputs are unloaded.
5. Input signals switch from 0V to 3V with a rise/fall time less than 3 ns, clocks and clock enables switch at 20 MHz, while the data inputs switch at 10 MHz.
Outputs are unloaded.
6. All input signals are connected to V_CC. All outputs are unloaded. Read and write clocks switch at maximum frequency (f_MAX).
7. Tested initially and after any design or process changes that may affect these parameters.
