SN74LS283D

Specialty Logic Overview

The SN74LS283D is a low-power Schottky (LS) 4-bit binary full adder manufactured by Texas Instruments. It accepts two 4-bit binary words and a carry input to generate sum outputs and a carry output from the most significant bit. The device operates with either active HIGH or active LOW operands, supporting positive or negative logic. It features internal carry lookahead for fast carry propagation. The component is housed in a 16-pin Small Outline Integrated Circuit (SOIC) package and complies with RoHS standards.
