74LS76 Dual J-K Flip-Flop – DIP-16

The 7476 is a TTL logic integrated circuit containing two independent master-slave J-K flip-flops in a single package. Each flip-flop supports standard J-K logic operation with asynchronous preset and clear inputs for immediate state control. Its master-slave architecture ensures stable operation by eliminating race conditions during clock transitions, making it highly reliable for sequential logic applications. The 7476 is widely used in counters, frequency dividers, digital control systems, and state machine designs. Operating on a standard 5V TTL supply, it is ideal for both educational and industrial digital electronics.
