74LS73 or 7473 IC-Dual JK Flip-Flop
The ’73, and ‘H73, contain two independent J-K flip-flops with individual J-K, clock, and direct clear inputs. The ’73, and ‘H73, are positive pulse-triggered flip-flops. J-K 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.
