No change from the previous setup
Don’t care
This setup is unstable and will change when either set of
reset return to the high–level
Low–to–high clock transition.
Data entering the flip–flop requires two clock cycles to
arrive at the output (see logic diagram)
ABSOLUTE MAXIMUM RATINGS
(Operation beyond the limit set forth in this table may impair the useful life of the device. Unless otherwise noted these limits are over the
operating free air temperature range.)
