TIMING CHARACTERISTICS
(Unipolar input range, V
+3V, 8-Bit ADC with 1µA Power-Down
Note 6: Input control signals are specified with t r = t f = 5ns, 10% to 90% of +3.0V, and timed from a voltage level of 1.3V. Timing
Note 7: See Figure 1 for load circuit. Parameter defined as the time required for the output to cross 0.66V or 2.0V.
Note 8: See Figure 2 for load circuit. Parameter defined as the time required for the data lines to change 0.5V.
