Overview
The LMV331M7X is a single-channel general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features an open-drain output configuration compatible with CMOS, TTL, and other logic families. The device exhibits a maximum propagation delay of 600 ns and a typical operating supply current of 120 µA. Input characteristics include a maximum input offset voltage of 7 mV and a maximum input bias current of 250 nA. It is housed in a compact SC-70-5 surface-mount package and is rated for operation across a temperature range of -40°C to +85°C.
Feature Summary
- Low-voltage operation capability supporting systems powered between 2.7 V and 5.5 V
- Open-drain output stage allowing flexible interfacing with various digital logic levels
- Compact SC-70-5 surface-mount packaging designed for space-constrained applications
Applications
- General-purpose signal comparison circuits
- Threshold detection systems
- Voltage monitoring applications
Procurement Notes
Verify component authenticity through authorized channels as the LMV331M7X is designated as Not Recommended for New Designs (NRND) and has been discontinued by the manufacturer. Confirm RoHS compliance status, as specific documentation indicates non-compliance for this variant. Ensure replacement strategies account for the obsolete status when planning long-term production cycles.
Selection Notes
Select this component only if legacy compatibility or specific form-factor requirements necessitate the SC-70-5 package and single-channel architecture. Evaluate the discontinuation status against product lifecycle requirements. Consider the LMV331M7X/NOPB as a verified direct substitute from the same manufacturer if availability permits, noting potential differences in environmental compliance specifications.
Part Context
This part belongs to the LMV3xx series, which represents low-voltage versions of industry-standard comparators like the LM339 and LM393. The series is characterized by reduced power consumption and operation at lower supply voltages compared to traditional bipolar counterparts. The LMV331 specifically provides a single-channel solution within this family, maintaining similar functional performance while optimizing for modern low-power electronic designs.
Replacement Considerations
The LMV331M7X/NOPB is listed as a direct substitute by Texas Instruments. Verify pinout and electrical parameter equivalence before implementation.
