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.

These full adders perform the addition of two 4-bit binary
numbers. The sum (R) outputs are provided for each bit and
the resultant carry (C4) is obtained from the fourth bit.
These adders feature a full internal look ahead across all four
bits. This provides the system designer with a partial lookahead
performance at the economy and reduced package
count of a ripple-carry implementation.
