↑ : Low to high transition

Notes: 1. Output level before the indicated steady state input conditions were established.

2. Output level before the indicated steady state input conditions were established, provided that

CLKAB was high before LEAB went low.

3. A to B data flow is show; B to A flow is similar but uses OEBA, LEBA, and CLKBA.
