IC 74LS83 4 Bit Binary Full Adder
The 74LS83 is a TTL-based 4-bit binary full adder IC that performs fast, parallel binary addition of two 4-bit numbers with a carry input and carry output. It is widely used in digital computing systems to build Arithmetic Logic Units (ALUs), binary counters, and data processing units where high-speed arithmetic operations are needed.
What sets this IC apart is its carry-lookahead feature, allowing for faster addition by minimizing propagation delay—a critical factor in performance-sensitive logic circuits. The IC consists of four full adders connected in cascade, with an input carry that facilitates multi-bit additions across multiple 74LS83 units.
Packaged in a DIP-16 format, the IC is suitable for breadboards and prototyping with microcontrollers like ATmega328P, PIC16F887, or embedded in educational and industrial-grade digital systems.
You can easily integrate this IC into digital logic circuits along with other components from our IC’s collection or electronics components.
