Note

The ‘‘Absolute Maximum Ratings’’ are those values

beyond which the safety of the device cannot be guaran-

teed The device should not be operated at these limits The

parametric values defined in the ‘‘Electrical Characteristics’’

table are not guaranteed at the absolute maximum ratings

The ‘‘Recommended Operating Conditions’’ table will define

the conditions for actual device operation

Note 1

The ADDRESS setup time is the time before the negative ENABLE transition that the ADDRESS must be stable so that the correct latch is addressed

without affecting the other latches
