Overview
The LMV331M5/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, open-drain, and TTL logic families. The device exhibits a maximum propagation delay of 600 ns and a typical output current capability of 84 mA at 5 V. Static current consumption is limited to a maximum of 120 µA, while input bias current reaches 0.25 µA at 5 V. It functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Provides standard general-purpose comparison functionality with flexible logic compatibility
- Supports low-voltage operation suitable for portable and battery-powered applications
- Delivers high output drive capability through open-collector configuration
Applications
- General-purpose signal threshold detection
- Low-voltage monitoring circuits
- Simple digital interface level shifting
Procurement Notes
Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm package designation SC-74A (SOT-23-5) matches board layout requirements. Check current lifecycle status, as availability may vary due to production updates or obsolescence notices. Ensure supply chain sources provide authentic components with traceable manufacturing data.
Selection Notes
Select this component when a single comparator with open-collector output is required for low-power designs. Consider the 600 ns propagation delay for timing-sensitive applications. Evaluate the 2.7 V minimum supply voltage against system power rails. Verify that the SOT-23-5 package fits the available footprint constraints.
Part Context
This part belongs to the LMV331-N series of comparators. It shares functional similarities with other members like the LMV331M7X but differs in packaging and specific electrical characteristics. The NOPB suffix typically denotes environmental compliance adjustments rather than functional changes compared to earlier versions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material.
