Connection Diagram

Pin Descriptions

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 and CLKBA. OEBA is active LOW.

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.
