LM311D TI Comparator | 8-SOIC | Single, Open Collector, 200ns

Product Overview

The LM311D from Texas Instruments is a high-speed, single-channel voltage comparator designed for applications requiring fast response and low input offset. Housed in an 8-SOIC package, it features an open-collector output that allows flexible interfacing with various logic families. With a typical response time of 200 ns and a wide supply voltage range from 5V to 30V (or ±15V dual supply), the LM311D is ideal for precision signal detection, zero-crossing detectors, and level translators in industrial and automotive systems.
