The SN74LS76A offers individual J, K, Clock Pulse, Direct Set and
Direct Clear inputs. These dual flip-flops are designed so that when
the clock goes HIGH, the inputs are enabled and data will be accepted.
The Logic Level of the J and K inputs will perform according to the
Truth Table as long as minimum set-up times are observed. Input data
is transferred to the outputs on the HIGH-to-LOW clock transitions.
