X : Immaterial
Z : High impedance
↓ : High to low 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 low before LEAB went low.
3. A to B data flow is show; B to A flow is similar but uses OEBA, LEBA, and CLKBA.
