74ls76 Ic Dual J-K Flip-Flop IC
The 74LS76 is a Dual J-K Flip-Flop designed for use in sequential logic circuits. Each flip-flop includes asynchronous preset (PRE) and clear (CLR) functions, as well as J, K, and clock (CLK) inputs. These flip-flops are positive-edge triggered, meaning output changes occur on the rising edge of the clock signal.
Its TTL compatibility ensures reliable interfacing with other logic ICs such as the 74LS series. The 74LS76 is built in a DIP-16 package, making it suitable for breadboards, stripboards, and PCB designs.
This IC is often found in frequency dividers, toggle circuits, data storage elements, and digital counters. The inclusion of preset and clear allows direct control of output states without waiting for a clock pulse.
