NOTES:

1. A-to-B data flow is shown. B-to-A data flow is similar, but uses OEBA, LEBA, and

CLKBA.

2. H = HIGH Voltage Level

L = LOW Voltage Level

X = Don’t Care

Z = High-Impedance

↑ = LOW-to-HIGH Transition

3. Output level before the indicated steady-state input conditions were established

4. Output level before the indicated steady-state input conditions were established,

provided that CLKAB was LOW before LEAB went LOW.
