Note 4: A-to-B data flow is shown; B-to-A flow is similar but uses OEBA,
LEBA, CLKBA, and CLKENBA.
Note 5: Output level before the indicated steady-state input conditions
were established.
Note 6: Output level before the indicated steady-state input conditions
were established, provided that CLKAB was HIGH before LEAB went LOW.
