[1]

H = HIGH voltage level;

h = HIGH voltage level one set-up time prior to the HIGH-to-LOW clock transition;

L = LOW voltage level;

l = LOW voltage level one set-up time prior to the HIGH-to-LOW clock transition;

NC = no change;

X = don’t care;

Z = high-impedance OFF-state;

↑ = LOW-to-HIGH clock transition.
