A-to-B data flow is shown. B-to-A is similar, but uses OEBA, LEBA, and CP. It is not recommended to
set OEAB and OEBA LOW at the same time.
X — don’t care
H — HIGH voltage level
L — LOW voltage level
Z — high-impedance OFF-state
Output level before the indicated steady-state input conditions were established, provided that CP
was HIGH before LEAB went LOW.
