= t
f
= 5ns, 10% to 90% of 5V, and timed from a voltage level of 1.6V.
Note 5: See Figure 1 for load circuit. Parameter defined as the time required for the output to cross 0.8V or 2.4V.
Note 6: See Figure 2 for load circuit. Parameter defined as the time required for the data lines to change 0.5V.
Note 7: Also defined as the Minimum Address-Valid to Convert-Start Time.
