ABSOLUTE MAXIMUM RATINGS(1)

NOTE:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS 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 extended periods may affect reliability.

NOTE:

1. As applicable to the device type.

NOTES:

1. H = HIGH Voltage Level

X = Don’t Care

L = LOW Voltage Level

Z = High-Impedance

↑ = LOW-to-HIGH transition

2. A-to-B data flow is shown. B-to-A data flow is similar but uses OEBA, LEBA, CLKBA,

and CLKENBA.

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 HIGH before LEAB went LOW.
