F

= 20ns (10% to 90% of +5V) and timed from a 1.6V voltage level.

Note 6:

Measured with load circuits of Figure 1 and defined as the time required for an output to cross 0.8V or 2.4V.

Note 7:

Defined as the time required for the data lines to change 0.5V when loaded with the circuits of Figure 2.
