= 5V, T
A
= +25°C. For conditions shown as Min and Max, use
the appropriate value specified under recommended operating conditions.
Note 3. Clear is tested with preset high and preset is tested with clear high.
Note 4. Not more than one output should be shorted at a time.
Note 5. With all outputs open, I
CC
is measured with the Q and Q outputs high in turn. At the time of
measurement, the clock input is grounded.
