LM311PSR TI Comparator | 8-SO | Single, Open Collector, 200ns Response

Product Overview

The LM311PSR from Texas Instruments is a high-speed, single-channel voltage comparator designed for applications requiring fast response and flexible output configurations. Housed in an 8-pin SOIC package, this device features an open-collector output that allows for wired-OR connections and compatibility with various logic families. With a typical response time of 200 ns, it is suitable for precision threshold detection, zero-crossing detectors, and pulse-width modulators. The LM311PSR operates from a single 5V supply or dual supplies up to ±15V, making it versatile for both analog and digital systems.
