LMV331M7

Overview

The LMV331M7 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 consumes a maximum static current of 120 µA. The device features an open collector/open drain output compatible with CMOS, TTL, and other logic families. Key electrical specifications include a maximum input offset voltage of 7 mV at 5 V, a maximum input bias current of 0.25 µA, and a propagation delay of up to 600 ns. It is housed in a compact SC-70-5 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Low voltage operation capability ranging from 2.7 V to 5.5 V for battery-powered applications
• Open collector output interface ensuring compatibility with various digital logic families
• Compact SC-70-5 surface-mount packaging designed for space-constrained circuit designs

Applications

• General-purpose signal comparison in low-voltage electronic systems
• Threshold detection circuits requiring minimal power consumption
• Interface between analog sensors and digital logic controllers

Procurement Notes

Verify component authenticity through authorized distributors as the LMV331M7 is listed as obsolete or not recommended for new designs. Confirm RoHS compliance status and check for available direct replacements such as the LMV331M7X/NOPB variant. Ensure that the specific suffix matches the required tape-and-reel or cut-tape packaging format for your assembly process.

Selection Notes

Select this component when a single-channel comparator with low quiescent current is required. The open-drain output allows flexible pull-up resistor selection for different logic levels. Consider the 7 mV input offset voltage specification for precision requirements. Verify that the SC-70-5 footprint aligns with existing PCB layout constraints and thermal management needs.

Part Context

The LMV331M7 belongs to the LMV3xx series, which are low-voltage counterparts to the industry-standard LM339/LM393 family. This series provides reduced current consumption while maintaining functionality in single-supply environments. The M7 suffix specifically denotes the SC-70-5 package configuration used by Texas Instruments for this single-channel variant.

Replacement Considerations

The LMV331M7/NOPB is identified as a direct substitute part number. Verify pinout compatibility and electrical parameter equivalence before substitution. Check if the replacement maintains the same SC-70-5 package dimensions and lead finish specifications.
