Measurement points are given in Table 10.
t_PLH and t_PHL are the same as t_pd.
t_TLH = LOW to HIGH output transition time; t_THL = HIGH to LOW output transition time.
The shift clock (SHCP) to output (Q7S) propagation delays, the shift clock pulse
width, the maximum shift clock frequency, and output transition times
