LMV331M5X-TI

Overview

The LMV331M5X-TI is a single-channel general-purpose comparator manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device features an open-collector output compatible with CMOS, TTL, and other logic families. Key electrical specifications include a maximum propagation delay of 600 ns, a typical output current of 84 mA at 5 V, and a maximum input bias current of 0.25 µA at 5 V. The quiescent current is limited to a maximum of 120 µA. It is housed in a SOT-23-5 (SC-74A) surface-mount package and supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Low voltage operation suitable for portable applications
• Open-collector output interface for flexible logic compatibility
• Compact SOT-23-5 packaging for space-constrained designs

Applications

• Analog-to-digital signal conversion circuits
• Threshold detection systems
• Simple comparator circuits for level sensing

Procurement Notes

Verify the specific suffix 'M5X' against the manufacturer's official datasheet to confirm tape-and-reel packaging and pinout configuration. Ensure the component meets the required operating temperature range and supply voltage specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when a low-voltage, single-channel comparator is required with open-collector outputs. It is appropriate for designs needing minimal power consumption and small footprint. Verify that the load can be driven within the specified output current limits and that the propagation delay meets the system timing requirements.

Part Context

This part belongs to the LMV331 family of general-purpose, low-voltage comparators. It is functionally related to the LMV393 (dual) and LMV339 (quad) variants, offering similar performance characteristics across different channel counts. The series is designed for applications requiring high speed and low power in compact packages.

Replacement Considerations

Direct substitutes include the LMV331MX and LMV331M5X from Texas Instruments or National Semiconductor. Cross-manufacturer equivalents such as the MAX9647 may offer comparable specifications but require verification of pin compatibility and electrical parameters.
