H = HIGH Voltage Level

L = LOW Voltage Level

X = Immaterial (HIGH or LOW, inputs may not float)

Z = High Impedance

Note 2: A-to-B data flow is shown; B-to-A flow is similar but uses OEBA,

LEBA, CLKBA, and CLKENBA.

Note 3: Output level before the indicated steady-state input conditions

were established.

Note 4: Output level before the indicated steady-state input conditions

were established, provided that CLKAB was HIGH before LEAB went LOW.
