H = HIGH voltage level;

L = LOW voltage level;

X = don’t care;

Z = high-impedance OFF-state;

↑ = LOW-to-HIGH clock transition

[2]

Output level before the indicated steady-state input conditions were established.

[3]

Output level before the indicated steady-state input conditions were established, provided that CPAB or

CPBA was LOW before LEAB or LEBA went LOW.
