Overview
The LMV339IDT is a quad low-voltage analog comparator manufactured by STMicroelectronics. It operates with a supply voltage ranging from 2.7 V to 5 V and features a typical quiescent current of 124 µA. The device exhibits a propagation delay of 1 ms and includes an open-drain output configuration. It is housed in a SOIC-14 surface-mount package and is designed for operation across a temperature range of -40°C to +125°C.
Feature Summary
- Quad channel architecture providing four independent comparison functions within a single integrated circuit.
- Low voltage operation capability supporting systems powered between 2.7 V and 5 V.
- Open-drain output structure allowing flexible interfacing with various logic families.
Applications
- Battery-powered portable electronics requiring low power consumption
- Space-constrained embedded designs utilizing compact surface-mount packaging
- General-purpose signal conditioning circuits operating at low voltages
Procurement Notes
Verify the specific suffix IDT corresponds to the SOIC-14 package and reel quantity requirements. Confirm that the 124 µA current specification aligns with your system's power budget, as this differs from other variants in the series. Ensure thermal management supports the specified industrial temperature range during operation.
Selection Notes
Select this component when a quad comparator is required for low-voltage applications. It serves as a low-power alternative to standard LM339 devices. Consider the open-drain output requirement for pull-up resistor implementation. Verify compatibility with the target PCB footprint for the SOIC-14 package.
Part Context
This part belongs to the LMV3xx family, which are low-voltage versions of the industry-standard LM339/LM393 comparators. The LMV339 specifically provides four channels, distinguishing it from the single-channel LMV331 and dual-channel LMV393. It shares the same functional pinout but offers improved performance at lower supply voltages.
Replacement Considerations
LMV339IP (TSSOP-14 package variant). TS339IDT (Higher voltage range up to 16 V, different response time).
