74LS76 comes with dual JK flip-flops. JK flip flops are widely used in daily electronics devices by many methods but the basic operation of the JK flip flop is to store a bit. JK flip flop allows it to store a bit and then allows it to use for further functions. in digital electronics circuits. JK flip flop is one of the popular flip flops due to its clock input, pre-set, and clear functionalities. The JK flip-flop changes its state under the clock pulse signal. The clock signal can be either a positive edge or a negative edge. The clock pulse gives multiple advantages to the flip-flop. 74LS76 also has provided a feature to neglect or prevent invalid outputs.
Pin Description of 74LS76:
| Pin Number | Pin Name | Description |
