LMV339IPWRE4

Overview

The LMV339IPWRE4 is a quad low-voltage analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V, supporting single or dual power configurations. The device features four independent channels housed in a 14-pin TSSOP package. Key electrical parameters include a maximum propagation delay of 600 ns and a typical quiescent current of 350 µA. Input offset voltage is specified at a maximum of 7 mV at 5 V, with an input bias current of 0.25 µA. The output stage utilizes an open-collector configuration capable of sourcing up to 84 mA at 5 V.

Feature Summary

• Low-voltage operation optimized for 2.7 V to 5.5 V power supplies
• Quad differential comparator architecture with open-collector outputs
• Extended industrial temperature range from -40°C to +125°C

Applications

• Battery-powered portable electronics
• Low-voltage signal conditioning circuits
• Space-constrained embedded systems

Procurement Notes

Verify the specific suffix IPWRE4 against the manufacturer's official datasheet to confirm the TSSOP-14 package and tape-and-reel packaging format. Ensure compatibility with RoHS3 standards as indicated in public documentation. Cross-reference the part number with authorized distributors to confirm current availability status, as some variants may be subject to production changes or obsolescence notices.

Selection Notes

Select this component when designing circuits requiring low supply voltages between 2.7 V and 5.5 V. The open-collector output necessitates an external pull-up resistor for proper logic level interfacing. Consider the 600 ns propagation delay for timing-sensitive applications. Verify that the TSSOP-14 footprint matches the PCB layout requirements and that the thermal performance is adequate for the intended operating environment.

Part Context

The LMV339 series represents the low-voltage counterpart to the industry-standard LM339 comparators. Designed for modern low-power applications, it offers reduced current consumption while maintaining comparable functionality. The RE4 suffix typically denotes environmental compliance, specifically adhering to RoHS directives. This variant integrates four comparators into a compact surface-mount package suitable for high-density board designs.

Replacement Considerations

Publicly confirmed substitute part numbers include LMV339IPWR.
