ister packages while allowing reduced clock drive
fan-out and transition-time requirements. A third
cascading option makes use of the Q’ output from
the 1/2 stage, which is available on the next nega-
tive-going transition of the clock after the Q output
occurs. This delayed output, like the delayed clock
CLD, is used with clocks having slow rise and fall
times.

Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at theseor any other conditions abovethose indicated in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for external periods may affect device reliability.
