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 Setup Time ‘‘t
s
(L)’’ and Hold Time ‘‘t
h
(H)’’ between the Count Enable (CEP and CET) and the Clock (CP) indicate that the HIGH-to-LOW transition of
the CEP and CET must occur only while the Clock is HIGH for conventional operation.
Note 2:
The Setup Time ‘‘t
s
(H)’’ and Hold Time ‘‘t

(L)’’ between the Parallel Enable (PE) and Clock (CP) indicate that the LOW-to-HIGH transition of the PE must
occur only while the Clock is HIGH for conventional operation.
