T iming specifications in
bold
print are 100% production tested. All other times are sample tested at +5
°
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.

t
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.
3
t
is derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit of Figure 1. T he measured number is then extrap-
olated back to remove the effects of charging or discharging the 100 pF capacitor. T his means that the time, t
7
, quoted in the T iming 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.
