Design a Custom BoardAbout This Component
Dual 2-to-4 line decoder/demultiplexer IC in 16-pin SOIC package. Decodes 2-bit binary input to select one of four active-low outputs. HCT logic family provides TTL-compatible inputs with CMOS power efficiency. Ideal for address decoding, output selection, and multiplexing applications in digital circuits.
Package: SOIC-16 (3.9×9.9mm) · 16 pins
Why does this need a breakout?
The 1.27mm pin pitch on this 16-pin package makes hand-soldering impractical and breadboard mounting impossible. A breakout board brings the pins to standard 2.54mm spacing, enabling quick prototyping of RS-232/RS-485 transceivers, ADCs, and line drivers without requiring surface-mount soldering skills or PCB fabrication.
