Notes:
2.
The VIH and VIL 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 VSS.
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 (fMAX), while data inputs
switch at fMAX/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 VCC. All outputs are unloaded. Read and write clocks switch at maximum frequency (fMAX).
7.
Tested initially and after any design or process changes that may affect these parameters.
