1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification is
not implied. Exposure to absolute maximum rating conditions for ex-
tended periods may affect reliability.

1. A-to-B 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 conditions were
established.
3. Output level before the indicated steady-state input conditions were
established, provided that CLKAB was HIGH before LEAB went LOW.
4. H = HIGH Voltage Level
L = LOW Voltage Level
X = Don't Care
Z = High Impedance
↑ = LOW-to-HIGH Transition
