=
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.
