[1] H = HIGH voltage level;
L = LOW voltage level;
X = don’t care;
Z = high-impedance OFF-state;
↑ = LOW-to-HIGH clock transition.
[2] Y0 = Output level before the indicated steady-state input conditions were established, provided that CP is high before LE goes low.
[3] Y0 = Output level before the indicated steady-state input conditions were established.
