Procurement Notes
Verify the specific manufacturer datasheet revision and official ordering suffixes to ensure compatibility with design requirements. Confirm package dimensions and thermal characteristics against the target PCB layout specifications before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring multiple comparators in a compact surface-mount footprint. Ensure the circuit design accommodates the open-drain output requirement by including appropriate pull-up resistors. Verify that the operating voltage remains within the specified 2.7 V to 5 V range for optimal performance.
Part Context
This part belongs to the LMV3xx series, which serves as the low-voltage counterpart to the industry-standard LM339 family. The series offers reduced power consumption while maintaining comparable functionality in smaller packages suitable for space-constrained designs.
