Guaranteed by design. All input signals are specified with t
from 4.75 V to 5.25 V.
Mark/space ratio for the SCLK input is 40/60 to 60/40.
Measured with the load circuit in Figure 3 and defined as the time required for the output to cross 0.4 V, or 0.7 × V

back to remove the effects of charging or discharging the 50 pF capacitor. This means that the time, t
