(1) Typical values represent the likely parametric nominal values determined at the time of characterization. Typical values depend on the
application and configuration and may vary over time. Typical values are not ensured on production material.
(2) 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.
