ABSOLUTE MAXIMUM RATINGS(1)

NOTES:

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.

2. VCC terminals.

3. All terminals except VCC.

NOTES:

1. H = HIGH Voltage Level

L = LOW Voltage Level

X = Don’t Care

Z = High Impedance

↑ = LOW-to-HIGH transition

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

provided that CLK is HIGH before LE went HIGH.

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