NOTES
1
Sample tested during initial release and after any redesign or process change that may affect this parameter. 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 Figures 16, 17, 20 and 21.
3
These figures are measured with the load circuit of Figure 3. They are defined as the time required for D
OUT
to cross 0.8 V or 2.4 V for V
DD
= 5 V 10% and 0.4 V
or 2 V for V
= 3 V 10%, as quoted on the specifications page of this data sheet.
4
These times are derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit of Figure 3. 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.
Specifications subject to change without notice.
