Design a Custom BoardAbout This Component
Quad 2-input multiplexer with 3-state outputs in 16-pin SO package. Features TTL-compatible inputs, wide 2.0V–6.0V supply range, and automotive AEC-Q100 Grade 1 qualification. Suitable for data routing and bus interface applications in automotive and industrial systems.
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.
