Overview
The LMV331M5 is a single-channel general-purpose low-voltage 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, open-collector, and TTL logic families. Key electrical specifications include a maximum input bias current of 0.25 µA at 5 V, a typical output current of 84 mA at 5 V, and a maximum static current consumption of 120 µA. The device exhibits a maximum propagation delay of 600 ns and functions across a temperature range of -40°C to 85°C. It is housed in a surface-mount SOT-23-5 package.
Feature Summary
- Low voltage operation capability from 2.7 V to 5.5 V
- Open collector output interface supporting multiple logic families
- Compact SOT-23-5 surface mount packaging for space-constrained designs
Applications
- Low-voltage signal conditioning circuits
- Threshold detection systems
- Battery-powered monitoring applications
Procurement Notes
Verify the specific suffix M5 corresponds to the SOT-23-5 package variant when sourcing. Confirm component status as discontinued or obsolete through official manufacturer channels prior to procurement planning. Ensure compatibility with existing PCB footprints designated for SC-74A or SOT-753 packages. Validate that the open-collector output requirements align with the system pull-up configuration needs.
Selection Notes
Select this component for applications requiring low power consumption and small form factor in single-supply environments. Consider the open-collector output structure when designing interfacing logic levels. Evaluate the 600 ns propagation delay against system timing requirements. Verify thermal performance within the specified -40°C to 85°C operating range for the intended environment.
Part Context
The LMV331M5 belongs to the LMV3xx series, which serves as the low-voltage counterpart to the industry-standard LM339 and LM393 comparators. This family provides reduced current consumption compared to predecessors while maintaining functional compatibility. The single-channel configuration distinguishes it from dual (LMV393) and quad (LMV339) variants within the same product line.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation.
