NOTES
1
Sample tested during initial release and after any redesign or process change that may
affect this parameter. All input signals are specified with tr = tf = 5ns (10% to 90%)
and timed from a voltage level of 1.6V.
2
See timing diagram below and Serial Interface section of this data sheet.
3
Measured with the load circuit in Figure 1 and defined as the time required for the
output to cross 0.8V or 2.4V.
4
Derived from the measured time taken by the data outputs to change 0.5V when
loaded with the circuit in Figure 1. The measured number is then extrapolated back
to remove the effects of charging or discharging the 50pF capacitor. This means that
the time quoted in the timing characteristics is the true bus relinquish time of the
part and is independent of the bus loading.
5
Minimum time between read command and data read for all registers
except WAVFORM register. For WAVFORM register t
