Spread the components

The 74LS73 contain two independent J-K flip-flops with individual J-K, clock, and direct clear inputs. The 74LS73 is a positive pulse-triggered flip-flops. input is loaded into the master while the clock is high and transferred to the slave on the high-to-low transition. For these devices the J and K inputs must be stable while the clock is high. The 74LS73 contains two independent negative- edge-triggered flip-flops. The J and K inputs must be stable one setup time prior to the high- to-low clock transition for predictable operation. When the clear is low, it overrides the clock and data inputs forcing the Q output low and the output high. The 74LS73 is characterized for operation from O° C to 70° C.
