LMV339IPT

Overview

The LMV339IPT is a quad low-voltage analog comparator manufactured by STMicroelectronics, housed in a TSSOP-14 surface-mount package. It operates within a supply voltage range of 2.7 V to 5 V and consumes approximately 20 μA to 25 μA of quiescent current. The device features an open-drain output capable of sourcing up to 93 mA per channel, with a propagation delay of 200 ns. Input common mode range includes ground, and it offers ESD tolerance of 2 kV HBM and 200 V MM. Operating temperatures extend from -40°C to +85°C for this specific variant.

Feature Summary

• Low power consumption suitable for battery-operated systems
• Single-supply operation compatible with standard logic levels
• Open-drain output allows flexible interfacing with various voltage domains

Applications

• Battery-powered monitoring circuits
• Low-voltage signal processing
• Space-constrained embedded designs

Procurement Notes

Verify the specific temperature grade (-40°C to +85°C) against system requirements, as the broader LMV339 family supports up to +125°C. Confirm the TSSOP-14 package dimensions match the PCB footprint. Ensure the open-drain output configuration aligns with the pull-up resistor requirements of the target circuit interface.

Selection Notes

Select this component when space-saving SMD packaging is required alongside low voltage operation. The quad configuration provides multiple comparators in a single package, reducing board area compared to single-channel alternatives. Verify that the 200 ns propagation delay meets the speed requirements of the application, as faster options exist within the broader product line.

Part Context

This part belongs to the LMV3xx series, which are low-voltage counterparts to the industry-standard LM339/LM393. The 'I' suffix typically denotes the industrial temperature range, while 'PT' indicates the TSSOP-14 package type. It is designed to replace older bipolar comparators in modern low-power applications.

Replacement Considerations

Direct pin-compatible replacements include other quad low-voltage comparators from ST or competitors, provided they support the 2.7–5 V supply range and open-drain output. Verify that substitute parts meet the same 200 ns propagation delay and 20 μA current consumption specifications.
