Procurement Notes
Verify the component authenticity by checking the manufacturer's marking and datasheet alignment. Confirm the RoHS compliance status and lead-free designation as specified in the official documentation. Ensure the 8-SOIC package dimensions match the design requirements. Cross-reference the part number suffix RE4 with the manufacturer's ordering guide to confirm specific packaging and environmental attributes.
Selection Notes
Select this component when a high-speed differential comparator with multiple output drive options is required. Consider the 0°C to 70°C operating temperature range for commercial applications. Evaluate the 10mV maximum input offset voltage and 0.25µA bias current against system precision needs. Verify that the 3.5V to 30V supply range aligns with the available power rails in the target design.
Part Context
The LM311DRE4 belongs to the LM311 family of comparators from Texas Instruments. This series is known for its versatility and speed, offering various output configurations to interface with different logic families. The DRE4 suffix indicates a specific tape-and-reel packaging variant compliant with RoHS standards, designed for automated surface-mount assembly processes.
Replacement Considerations
Public confirmed substitute part numbers include LM311DRG4 and LM311DE4-NDR. Verify pinout compatibility and electrical specifications before substitution.
