4.In non-multiplexed address/data bus architectures, ALE should be held high so parameters tSALR, tHALR, tVL, tSLR, and tHLR are not applicable.

5.Parameter tHAR is not applicable if address latching is used.

6.When a set-up time is specified between an input and a clock, the set-up time is the time in nanoseconds from the 1.4 Volt point of the input to the 1.4 Volt point of the clock.

7.When a hold time is specified between an input and a clock, the hold time is the time in nanoseconds from the 1.4 Volt point of the input to the 1.4 Volt point of the clock.
