↑ : Low to high transition
Notes: 1. Output level before the indicated steady state input conditions were established, provided that
CLKAB was high before LEAB went low.
2. Output level before the indicated steady state input conditions were established.
3. A to B data flow is show; B to A flow is similar but uses OEBA, LEBA, and CLKBA.
