NOTES

Sample tested at 25
∞
C to ensure compliance. All input signals are specified with t
= t
= 5 ns (10% to 90% of AV
) and timed from a voltage level of 1.6 V.
See Figure 1. The 3 V operating range spans from 2.7 V to 3.6 V. The 5 V operating range spans from 4.75 V to 5.25 V.
2
Mark/Space ratio for the SCLK input is 40/60 to 60/40.
3
Measured with the load circuit of Figure 1 and defined as the time required for the output to cross 0.4 V or 0.7
￥
V
.
4
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. The measured number is then extrapolated
back to remove the effects of charging or discharging the 50 pF capacitor. This means that the time, quoted in the timing characteristics t
8
, is the true bus relinquish
time of the part and is independent of the bus loading.
