Note 2: A-to-B data flow is shown; B-to-A flow is similar but uses OEBA,
LEBA and CLKBA. OEBA is active LOW.
Note 3: Output level before the indicated steady-state input conditions
were established.
Note 4: Output level before the indicated steady-state input conditions
were established, provided that CLKAB was LOW before LEAB went LOW.
