See Figures 14, 15 and 16.
These numbers are measured with the load circuit of Figure 1. They are defined as the time required for the o/p to cross 0.8 V or 2.4 V for V
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, t
