DC CHARACTERISTICS
(VCC = 5.0V ± 10%)
Note b:
ICC1 and ICC3 are dependent on output loading and cycle rate. The specified values are obtained with outputs unloaded.
Note c:
ICC2 and ICC4 are the average currents required for the duration of the respective STORE cycles (tSTORE ).
Note d:
E
≥ VIH will not produce standby current levels until any nonvolatile cycle in progress has timed out.

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 condi-
tions 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.
