Note 4: Input control signals are specified with t_r = t_f = 5ns, 10% to 90% of 3V, and timed from a voltage level of 1.3V. Timing
delays get shorter at higher supply voltages. See the Conversion Time vs. Supply Voltage graph in the Typical Operating
Characteristics to extrapolate timing delays at other power-supply voltages.
Note 5: See Figure 1 for load circuit. Parameter defined as the time required for the output to cross 0.66V or 2.0V.
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.
