Q0 = the level of Q before the indicated input conditions were established.
TOGGLE: Each output changes to the complement of its previous level on each
active transition (pulse) of the clock.
*
This configuration is nonstable; that is, it will not persist whenpreset and clear inputs
return to their inactive (high) level.

*Not more than one output should be shorted at a time, and duration of the short-circuit should not exceed one second.
Note 1: With outputs open, ICC is measured with the Q and Q outputs high in turn. At the time of measurement, the
clock input is grounded.
