SN74LS155ADR TI Decoder/Demultiplexer | 16-SOIC | Dual 2-to-4 Line

Product Overview

The SN74LS155ADR from Texas Instruments is a dual 2-line to 4-line decoder/demultiplexer designed for high-performance memory decoding and data routing applications. Fabricated with advanced low-power Schottky technology, it offers a perfect balance of speed and power consumption. The device features two independent decoders, each with active-low outputs and enable inputs, providing flexibility in address decoding and signal demultiplexing. Housed in a compact 16-SOIC package, it is ideal for space-constrained designs in industrial, automotive, and telecommunications systems.
