TILMV331IDBVR
Overview
The LMV331IDBVR is a single, low-voltage general-purpose comparator featuring an open-collector output. It is designed to operate from 2.7V to 5.5V, making it suitable for modern low-power systems and portable electronics where space and power consumption are critical. The input common-mode voltage range includes ground, allowing for sensing in single-supply configurations.
Why Choose This Part
The LMV331 offers a significant reduction in supply current compared to older generations like the LM339 or LM393 while maintaining a fast 600ns propagation delay. Its open-collector output provides maximum design flexibility for wired-OR logic or driving loads up to 5.5V regardless of VCC. The ultra-small SOT-23-5 package saves significant PCB area in dense embedded designs.
Applications
Key Specifications
Getting Started
When designing with the LMV331, ensure a pull-up resistor is placed on the output as the open-collector stage cannot drive high on its own. For rapid prototyping, use a SOT-23 to DIP adapter for breadboard testing. Ensure bypass capacitors are placed close to the VCC pin to minimize noise during high-speed switching.
