LM311DR Texas Instruments High-Speed Analogue Comparator IC (SOIC-8)

A comparator's job looks simple, flip the output the instant one input crosses the other, but doing that cleanly at speed without chatter near the crossing point takes a properly designed chip, which is exactly the LM311's reputation. This genuine Texas Instruments version brings that same fast, clean switching to a SOIC-8 surface-mount package, for a finished PCB design that specifically wants traceable branded silicon over the generic DIP-8 part already in the catalog.
