Procurement Notes
Verify the specific suffix E4 indicates lead-free and RoHS compliance status according to current manufacturer documentation. Confirm the package type matches the required PCB footprint. Ensure the operating temperature grade aligns with the intended environmental conditions. Cross-reference the datasheet revision to confirm pinout and electrical characteristics remain consistent with existing designs.
Selection Notes
Select this component when a quad comparator with open-collector outputs is required for single-supply applications. It is suitable for designs needing a wide common-mode input range that extends to ground potential. Consider the propagation delay and offset voltage specifications against system timing requirements. Evaluate the thermal performance within the specified industrial temperature range during circuit design.
Part Context
This part belongs to the LMx39 series of quad differential comparators from Texas Instruments. It shares functional similarities with the LM139, LM339, and LM2901, differing primarily in temperature ranges and specific electrical parameters. The E4 suffix denotes a lead-free and RoHS-compliant version of the standard LM239ADR package.
