NOTES:
1. A-toB data flow is shown. B-to-A data flow is similar but
uses OEBA, LEBA, and CLKBA.
2. Output level before the indicated steady-state input condi-
tions were established.
3. Output level before the indicated steady-state input condi-
tions were established, provided that CLKAB was LOW
before LEAB went LOW.
4. H = High Voltage Level
L = Low Voltage Level
Z = High Impedance
↓ = HIGH-to-LOW Transition
