Design a Custom BoardAbout This Component
Low-power quad voltage comparator with four independent precision comparators in a 14-pin SO package. Operates from single supply (2-36V) or dual supplies (±1 to ±18V) with only 1.1mA quiescent current, ±1mV input offset voltage, and 25nA input bias current. Widely used for analog signal detection, window comparators, oscillator control, and level-shifting applications with TTL/CMOS-compatible outputs.
Package: SOIC-14 (3.9×8.7mm) · 14 pins
Why does this need a breakout?
Manual soldering of 1.27mm pitch SOIC-14 leads is tedious and error-prone; a breakout board eliminates this with pre-soldered pads and convenient 0.1-inch headers for breadboard prototyping. Ideal for developing capacitive touch sensor applications or other logic circuits without the fine-pitch assembly hassle.
