NOTES
1Sample tested at 25
°C to ensure compliance. All input signals are specified with tr = tf = 5 ns (10% to 90% of 5 V) and timed from a voltage level of 1.6 V.
2t
6 is measured with the load circuit of Figure 1 and defined as the time required for an output to cross 0.8 V or 2.4 V.
3t
7 is derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit of Figure 1. The measured number is then
extrapolated back to remove the effects of charging or discharging the 100 pF capacitor. This means that the time, t7, quoted in the Timing Characteristics
is the true bus relinquish time of the part and as such is independent of external bus loading capacitances.
Specifications subject to change without notice.

5%, VSS = –5 V
