Procurement Notes
Verify that the specific ordering suffix matches the required package type and RoHS compliance status. Confirm the manufacturer source directly through authorized distribution channels to ensure component authenticity. Check for any regional shipping restrictions or availability limitations before finalizing procurement plans.
Selection Notes
Select this component for designs requiring small footprint solutions due to its SC70 packaging. Ensure the application benefits from the wide operating temperature range suitable for automotive environments. Verify that the open-drain output configuration aligns with the system's pull-up requirements and logic levels.
Part Context
This part belongs to the LMX331/LMX393/LMX339 family of general-purpose comparators. These devices utilize advanced submicron CMOS technology to achieve superior performance compared to traditional BiCMOS or bipolar versions. The family offers various channel counts and package options to suit different space constraints.
Replacement Considerations
LMX331HAXK-T provides equivalent functionality with added internal hysteresis for improved noise immunity.
