Design a Custom BoardAbout This Component
Dual general-purpose voltage comparator in 8-SOIC surface-mount package. Each comparator features independent inputs with open-collector outputs suitable for driving logic gates or indicator circuits. Operates from ±15V or single supply up to 32V, ideal for analog signal detection, window comparators, and voltage threshold monitoring 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.
