1 Sample tested at initial release to ensure compliance. All input signals are measured with tr = tf = 1 ns (10% to 90% of 5 V) and timed from a voltage level of 1.6 V.
2 See Figure 9, Figure 10,and Figure 11.
3 Refer to the Standby Mode Operation section. The maximum specification of 6 ms is valid when using a 0.1 μF decoupling capacitor on the VREF pin.
4 Measured with the load circuit of Figure 2 and defined as the time required for an output to cross 0.8 V or 2.4 V.
5 These times are derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit shown in Figure 2. The measured number is
then extrapolated back to remove the effects of charging or discharging the 50 pF capacitor. This means that the times quoted in the timing characteristics are the
true bus relinquish times of the part, and as such, are independent of external bus loading capacitances.
