74LS76 DUAL JK FLIP-FLOP IC
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 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.

74LS76 Introduction
JK flip flops can be designed by manually using simple gates but to avoid circuit complexity the 74LS76 gives the advantages to use two JK flip flops at the same time. The JK flip flop in this 7476 IC also has a preset and clear function which allows the IC to bypass the clock and inputs and give the different outputs. 7476 is TTL based and can be operated with any TTL based device or any microcontroller. The IC comes in multiple packages that make the IC use any hardware according to the requirement. The multiple IC can be used to make further ICs in case of necessary.
