Design a Custom BoardAbout This Component
3-to-8 line decoder/demultiplexer in 16-pin SOIC package. Decodes 3-bit binary input to select one of 8 active-low outputs. Includes three independent enable inputs for cascading multiple devices. Operates on 4.5-5.5V supply with HCT logic levels. Commonly used in address decoding, output selection, and multiplexing applications.
Package: SOIC-16W (5.3mm wide) · 16 pins
Why does this need a breakout?
SO-16 packages feature 1.27mm pin pitch and surface-mount pads that are difficult to hand-solder reliably and impossible to breadboard. A breakout board breaks out all 16 pins to standard headers, enabling quick prototyping of RS485 drivers, DACs, comparators, and logic gates without soldering tiny leads or designing custom PCBs.
