SN74LS83N

Product Overview

SN74LS83N is a Texas Instruments (TI) 4-bit binary full adder integrated circuit from the Low-Power Schottky (LS) TTL logic family. The device performs arithmetic addition of two 4-bit binary numbers with carry input and carry output, providing high-speed carry propagation for digital computing and control applications. Featuring a 16-pin PDIP package, low power consumption and reliable TTL logic performance, SN74LS83N is widely used in arithmetic logic units (ALUs), digital systems, calculators, industrial controllers and legacy computer hardware.
