LM339PT in LM339 / LM393 Comparators Family
The LM339PT family represents a series of low-power quad voltage comparators manufactured primarily by STMicroelectronics. These devices are designed for operation from a single power supply over a wide range of voltages, though split-supply operation is also supported. Characterized by their four independent comparator circuits and open-collector outputs, these components are fundamental building blocks in analog signal processing, providing a cost-effective solution for voltage monitoring and logic level translation in industrial and consumer electronics.
Variants in This Sub-Family
Variants within the LM339 sub-family differ primarily in their packaging, such as the PT suffix denoting the TSSOP-14 thin shrink small outline package. Other variations include temperature grading for industrial versus automotive applications and minor differences in input offset voltage specifications. While the core quad architecture remains consistent, specific part numbers may offer enhanced ESD protection or AEC-Q100 qualification for harsh environment reliability.
