20. Test conditions assume signal transition time of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V, and output loading of the specified I
21. To access RAM, CE = L, UB = L, SEM = H. To access semaphore, CE = H and SEM = L. Either condition must be valid for the entire t
22. At any given temperature and voltage condition for any given device, t
23. Test conditions used are Load 3.
