LMV339MT/NOPB

Overview

The LMV339MT/NOPB is a quad general-purpose comparator manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2 V to 5.5 V, with a typical operating current of 75 uA per device. The component features four independent channels housed in a TSSOP-14 package. Each channel provides an open-collector output capable of sinking up to 10 mA. Key electrical specifications include a maximum input offset voltage of 7 mV and a response time of 200 ns. The device supports a common-mode voltage range extending down to -100 mV and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Quad configuration providing four independent comparison channels in a compact surface-mount package
• Low power consumption suitable for battery-operated applications with minimal quiescent current draw
• Wide single-supply voltage operation enabling compatibility with various logic families and power rails
• Open-collector outputs allow flexible interfacing with different load types and voltage levels

Applications

• Battery-powered monitoring systems requiring low standby current
• Threshold detection circuits for voltage level sensing
• On-off control mechanisms in consumer electronics
• Temperature sensing interfaces using thermal sensors

Procurement Notes

Verify the specific suffix 'MT' against the manufacturer's official documentation to confirm the exact tape-and-reel packaging quantity and variant designation. Ensure the ordering part number matches the required package style and temperature grade. Cross-reference the datasheet revision date to confirm parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a quad comparator with low supply current is required for space-constrained designs. The open-collector output necessitates an external pull-up resistor; ensure the selected resistor value aligns with the desired switching speed and load requirements. Verify that the system voltage remains within the specified 2 V to 5.5 V range for optimal performance.

Part Context

This device belongs to the LMV339 family of low-voltage comparators. It shares functional similarities with other quad comparators but distinguishes itself through its ultra-low power profile and wide operating voltage range. The TSSOP-14 package offers a smaller footprint compared to traditional DIP or SOIC options, making it suitable for dense PCB layouts.

Replacement Considerations

Direct replacements include LMV339IDR and LMV339M/NOPB. Verify pinout compatibility and electrical parameters such as response time and output current capability before substitution.
