You need two edge-triggered flip-flops that actually hold their state between clock pulses, and you want preset and clear lines so you can reset the circuit without pulling the power. The 74LS74 does exactly that—two D flip-flops in one 14-pin package, each with its own preset and clear inputs. No latching headaches, no mysterious state changes mid-build. Wire it up and trust it to hold
