Overview
The LMV339DTBR2G is a quad-channel, general-purpose, low-voltage comparator manufactured by onsemi. It operates within a supply voltage range of 2.7 V to 5.0 V and features an input common-mode voltage range that extends to ground. The device utilizes an open-drain output configuration suitable for wired-OR applications. It is housed in a TSSOP-14 package and is designed for portable applications requiring space-saving solutions.
Feature Summary
- Quad-channel architecture providing four independent comparison functions in a single package
- Input common-mode voltage range includes ground potential for single-supply operation
- Open-drain output stage enables flexible logic interfacing and wired-OR configurations
- Low quiescent current consumption optimized for battery-powered portable devices
Applications
- Battery monitors
- Notebooks and PDAs
- General purpose portable devices
- General purpose low voltage applications
Procurement Notes
Verify the specific ordering suffix DTBR2G corresponds to the TSSOP-14 package with tape and reel shipping configuration. Confirm RoHS compliance and Pb-Free status as indicated by the G suffix. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range for standard LMV339 variants.
Selection Notes
Select this component when multiple independent comparators are required in a compact form factor. The open-drain output necessitates an external pull-up resistor for proper high-state logic levels. Consider the propagation delay characteristics relative to signal transition speeds. Verify that the load current requirements do not exceed the output sink capabilities defined in the electrical specifications.
Part Context
This part belongs to the LMV3xx family, which includes the single-channel LMV331 and dual-channel LMV393. These devices serve as low-voltage alternatives to industry-standard LM339 and LM393 comparators. The family shares similar electrical characteristics but varies in channel count and available package options such as SC-70, TSOP-5, Micro8, SOIC, and TSSOP.

FAQ
What is the function of the open-drain output?
The open-drain output requires an external pull-up resistor to a positive supply voltage to switch properly and define the high logic state.
Does the input common-mode range include ground?
Yes, the input common-mode voltage range extends to ground, allowing for single-supply operation where inputs can be at or near 0 V.
