LM311H TI Comparator | TO-99-8 | Single, Open Collector, 200ns

Product Overview

The LM311H is a high-speed voltage comparator from Texas Instruments, designed for applications requiring fast response and versatile output configurations. Housed in a TO-99-8 metal can package, it features an open-collector output that can be pulled up to any voltage up to 50V, making it compatible with various logic families. The device operates from a single 5V supply or dual supplies up to ±15V, with a typical response time of 200ns. Its low input offset voltage (2mV typical) and high input impedance make it suitable for precision threshold detection, zero-crossing detectors, and waveform shaping circuits.
