Dual JK Flip−Flop with Set and Clear
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.

Voltage Level L, I = LOW
Voltage Level X = Immaterial l, h (q) = Lower case letters indicate the state of the referenced input i, h (q) = (or output) one setup time prior to the HIGH−to−LOW clock transition
