Design a Custom BoardAbout This Component
Dual voltage comparator in 8-pin SOIC package with open-collector outputs and independent supply pins for each comparator. Features wide input voltage range and fast response time suitable for analog signal processing, level detection, and window comparators in automotive and industrial applications.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
