Design a Custom BoardAbout This Component
3-to-8 line decoder/demultiplexer that converts 3 binary address inputs (A0-A2) into 8 mutually exclusive outputs (Y0-Y7). Features three enable inputs for easy cascading and demultiplexing capability. Operates from 2.0V to 6.0V with low power CMOS consumption, making it ideal for memory chip select decoding and address decoding applications.
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.
