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:
RELEASE TIME: t
RELEASE
is defined as the maximum time allowed for the logic level to be present at the logic input prior to the clock transition from low to
high in order for the flip-flop(s) not to respond.
