H = High level (steady state). L = Low level (steady state). x = Irrelevant.
t = Transition from low to high level.
↓ = Transition from high to low level.
QO = 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 unstable; that is, it will not persist when preset and clear inputs return to their inactive (high)
level.
Device types O5 and O6 (each flip-flop)
t = device type O6 only.
