LMV331M5X/NOPB

Overview

The LMV331M5X/NOPB 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-collector output compatible with CMOS, TTL, and open-drain logic families. The device draws a maximum quiescent current of 120 µA and supports a typical output sink current of 84 mA at 5 V. Key electrical specifications include a maximum propagation delay of 600 ns, a maximum input offset voltage of 7 mV, and a maximum input bias current of 0.25 µA at 5 V. It is housed in a SC-74A (SOT-753) surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides rail-to-rail input capability for low-voltage signal processing applications
• Features an open-collector output interface supporting multiple logic standards including CMOS and TTL
• Designed for low-power operation with minimal quiescent current consumption

Applications

• Battery-powered portable electronic devices requiring low supply voltage operation
• Threshold detection circuits in consumer electronics
• Signal conditioning stages in microcontroller-based systems

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the 'M5X' designation corresponds to the SC-74A/SOT-753 tape-and-reel packaging format required for automated assembly processes. Cross-reference the exact part number against the latest Texas Instruments lifecycle notices to ensure availability and active manufacturing status before finalizing procurement plans.

Selection Notes

Select this component when a single comparator with rail-to-rail inputs is required in a compact SOT-753 footprint. Ensure the application voltage remains within the 2.7 V to 5.5 V operational window. Consider the open-collector output requirement for external pull-up resistor implementation if interfacing with different logic voltage levels than the supply voltage.

Part Context

This device belongs to the LMV331-N family of general-purpose comparators from Texas Instruments. It serves as a low-cost, low-voltage alternative to standard bipolar comparators, offering improved power efficiency and compatibility with modern low-voltage digital logic families while maintaining robust performance in space-constrained designs.

Replacement Considerations

The LMV331M5X/NOPB is functionally equivalent to the LMV331M5X. Verify that any substitute maintains the same SOT-753 pinout and electrical characteristics to ensure direct interchangeability without circuit modification.
