LM311PSRE4

Overview

The LM311PSRE4 is a quad differential comparator manufactured by Texas Instruments. It features four independent comparators in an 16-pin PSOP package. The device supports strobe inputs for output control and operates with supply voltages up to 30V. It includes open-collector outputs compatible with various logic families.

Feature Summary

• Quad differential comparator architecture
• Strobe input functionality for output control
• Open-collector output configuration
• Wide single or split supply voltage operation

Applications

• Voltage monitoring systems
• Logic level shifting circuits
• Peak detection applications
• Time delay generation

Procurement Notes

Verify the component authenticity through official Texas Instruments channels or authorized distributors. Confirm the package type matches the design requirements, as the PSOP variant may have specific footprint considerations. Ensure the datasheet version aligns with the manufacturing date code for accurate electrical specifications.

Selection Notes

Select this component when multiple independent comparison functions are required in a compact form factor. The quad configuration reduces board space compared to using individual single comparators. Consider the open-collector output requirement for pull-up resistor implementation in the circuit design.

Part Context

This part belongs to the LMx11 family of comparators from Texas Instruments. It shares functional similarities with other members like the LM311D and LM311N but differs in package style. The RE4 suffix indicates lead-free and RoHS compliance status.

Replacement Considerations

Direct pin-compatible replacements include LM311PSR and LM311PSRG4. Verify electrical parameters match before substitution. Alternative packages such as SOIC or DIP variants require schematic redesign due to pinout differences.
