Overview
The LM311M/NOPB is a high-speed, single-channel voltage comparator manufactured by Texas Instruments. It features an open-collector output and operates within a supply voltage range of 9V to 36V. The device exhibits a typical response time of 0.2 microseconds. Designed for surface-mount installation, it is housed in an 8-pin SOIC package with dimensions of 4.9mm length and 1.45mm height. The component supports operation at temperatures between 0°C and 70°C.
Feature Summary
- High-speed differential comparison capability
- Open-collector output configuration
- Wide single-supply voltage operation
Applications
- Voltage monitoring systems
- Zero-crossing detection circuits
- Logic interface adapters
Procurement Notes
Verify the specific suffix 'NOPB' indicates lead-free compliance during procurement. Confirm the SOIC-8 package variant matches the required footprint. Ensure the operating temperature range meets the application's thermal requirements. Cross-reference the manufacturer part number with official datasheets to validate specifications before integration.
Selection Notes
Select this component when a single-channel comparator with fast response is required. The open-collector output allows flexible interfacing with various logic families. Consider the 8-pin SOIC package for surface-mount assembly constraints. Evaluate the 9V to 36V supply range against system power availability.
Part Context
This device belongs to the LM311 family of comparators from Texas Instruments. It shares functional similarities with other members like the LM311DR but differs in packaging and compliance markings. The NOPB suffix denotes environmental compliance. It serves as a standard solution for general-purpose analog-to-digital conversion interfaces.
Replacement Considerations
Compatible substitutes include LM311DR and LM311DRE4. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement maintains the same package type and output configuration.
