Note a:

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 con-

ditions above those indicated in the operational sections of this

specification is not implied. Exposure to absolute maximum rat-

ing conditions for extended periods may affect reliability.

DC CHARACTERISTICS

(VCC = 5.0V ± 10%)

e

Note b:

ICC

1 and ICC3 are dependent on output loading and cycle rate. The specified values are obtained with outputs unloaded.

Note c:

ICC

2 and ICC4 are the average currents required for the duration of the respective

STORE

cycles (tSTORE ) .

Note d:

E

≥ V

IH will not produce standby current levels until any nonvolatile cycle in progress has timed out.

Note e:

VCC reference levels throughout this datasheet refer to VCC if that is where the power supply connection is made, or VCAP if VCC is connected

to ground.
