Note a:
Stresses greater than those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the device.
This a stress rating only, and functional operation of the
device at conditions above those indicated in the opera-
tional sections of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods
may affect reliability.

Note b: ICC1 and ICC3 are dependent on output loading and cycle rate. The specified values are obtained at minimum cycle 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.
