IC 7483 4-Bit Binary Adder IC

74LS83 designed as a high-speed 4-bit fuller Adder IC featuring carry out function. The IC has four independent stages of full adder circuits during a single package. It?s commonly utilized in applications where arithmetic operations are involved. Although today we?ve cheap microcontrollers that would perform all arithmetic operations required for our application, in period of time the ICs like Adder, Counter, flip-flops etc were used for same. In this manner the complexity and therefore the BOM cost of the circuit design will greatly go low. 74LS83 may be a Full Adder with Carry in and perform feature. It?s a four-stage 4-bit counter, meaning it?s four individual Full adder circuits each of 4-bit inside one package. It also can be easily cascaded if quite four stages are required. These full adders perform the addition of two 4-bit binary numbers. The sum (?) outputs provided for every bit and therefore the resultant carry (C4) obtained from the fourth bit. These adders feature full internal look ahead across all four bits. This gives the system designer a partial lookahead performance at the economy and a lower package count when using ripple-carry. Because the adder logic, including the carry, is implemented in its actual form, end-around carries are frequently achieved without the need of logic or level inversion. The 74LS83 multiplies the input carry by two 4-bit binary words (A and B). On the sum outputs (1?4) and outgoing carry (C4) outputs, the binary sum shows. 74LS83 Datasheet
