Truth Table
Note 1: A-to-B data flow is shown. B-to-A data flow is similar but uses OEBA, LEBA, CLKBA, and CEBA.
Note 2: Output level before the indicated steady state input conditions were established, provided that CLKAB was HIGH before LEAB went LOW.
Note 3: Output level before the indicated steady-state input conditions were established.
