The 74LS76 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.

NOTE: HC version is the high speed CMOS version which we may supply due to availability. It is fully compatible with LS version and one to one replaceable (not vice versa as HC version has more features)
