Product details

The Texas Instruments LM311PWLE is a voltage comparator — it compares two analog input voltages and outputs a digital logic-level signal indicating which is higher. This is the classic single-comparator building block used in zero-crossing detectors, level translators, window comparators, and oscillator circuits across industrial control, power-supply monitoring, and sensor interface boards.

For high-volume pick-and-place, check whether the LM311P (the tape-and-reel sibling) is a better fit for the feeder setup.

Frequently asked questions

What is the difference between LM311P and LM311PWLE?

The LM311PWLE ships in Bulk packaging (loose tubes/trays), while the LM311P typically comes in tape-and-reel. The silicon and comparator function are the same — the choice is about how the part feeds into your assembly line. For pick-and-place volume, the LM311P is the standard production variant; for bench builds and small runs, the LM311PWLE avoids reel waste.
