14. 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
15. 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
16. At any given temperature and voltage condition for any given device, t
17. Test conditions used are Load 3.
18. This parameter is guaranteed but not tested.
