LP311PG4

Overview

The LP311PG4 is a single low-power strobed differential comparator manufactured by Texas Instruments. It features an 8-pin PDIP package and operates within a supply voltage range of ±5V to ±18V. The device includes strobe inputs for output control, offering high-speed performance with a typical response time of 200ns. It supports differential or single-ended input configurations and provides open-collector outputs compatible with various logic families.

Feature Summary

• Integrates strobe functionality for precise output timing control
• Supports both differential and single-ended input signal processing
• Features open-collector outputs for flexible logic interfacing
• Designed for low-power consumption applications

Applications

• Voltage monitoring systems
• Window comparator circuits
• Logic level shifting interfaces
• Zero-crossing detectors

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the PDIP-8 package type matches your board layout requirements. Ensure the operating temperature range aligns with your system's environmental conditions before finalizing procurement specifications.

Selection Notes

Select this component when low power consumption and strobe-controlled outputs are required. Compare against standard comparators if speed is critical, noting the trade-off between power and response time. Verify input offset voltage specifications meet your sensitivity requirements for accurate threshold detection in noisy environments.

Part Context

This part belongs to the LP311 family of analog comparators from Texas Instruments. It shares functional similarities with the LM311 series but offers optimized power characteristics. The G4 suffix typically denotes environmental compliance features such as lead-free construction, distinguishing it from older non-compliant variants in the same product line.

Replacement Considerations

The LM311PWRG4 is a documented related variant within the Texas Instruments portfolio. Verify pin compatibility and electrical parameter equivalence before substitution. Check datasheet differences regarding response time and supply voltage ranges to ensure functional parity in your specific application circuit.
