(1) If the devices are connected in cascade and t_r or t_f is large, it may be critical to achieve the timing required for data transfer between two
cascaded devices.
7.10 Typical Characteristics
Figure 1: At low voltage levels (V_O), the output current (I_O) may be limited. Figure 1 shows the dependency of the output
current on the output voltage.
