Where to use 74LS83 IC
Although today we have cheap microcontrollers that could perform all arithmetic operations required for our application, in early days the ICs like Adder, Counter, flip-flops etc were used for same. This way the complexity and the BOM cost of the circuit design will greatly go low.
The 74LS83 is a Full Adder with Carry in and Carry out feature. It is a four stage 4-bit counter, meaning it has four individual Full adder circuits each of 4-bit inside a single package. It can also be easily cascaded if more than four stages are required.
Applications
High Speed Arithmetic operations
Miniature calculators
Counters
Simple logic control designs
