H = HIGH voltage level
h = HIGH voltage level one set-up time prior to the LOW-to-HIGH CP transition
L = LOW voltage level
I = LOW voltage level one set-up time prior to the LOW-to-HIGH CP transition
q = lower case letters indicate the state of the referenced input (or output)
one set-up time prior to the LOW-to-HIGH CP transition
X = don’t care
Z = high impedance OFF-state
