Absolute Maximum Ratings
(Note 4)
Note 4:
The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.

Note 6:
Times are with respect to the Write-Enable input. Write-Select time will protect the data written into the previous address. If protection of data in the
previous address, t

will result in data being written into that location. Depending on the duration of the input conditions, one or a number of previous addresses may have been
written into.
Note 7:
Latch time is the time allowed for the internal output of the latch to assume the state of new data. This is important only when attempting to read from
a location immediately after that location has received new data.
