LMV339DR2G

Overview

The LMV339DR2G 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 stage suitable for wired-OR applications. Typical performance at 5 V includes a propagation delay of 200 ns, quiescent current of 300 μA per channel, and a saturation voltage of 200 mV. It is housed in a 14-pin SOIC package.

Feature Summary

• Quad-channel architecture providing four independent comparators in a single package
• Input common-mode voltage range extends to ground potential
• Open-drain output configuration enabling wired-OR logic connections
• Low quiescent current consumption optimized for portable applications

Applications

• Battery monitors
• Notebooks and PDAs
• General purpose portable devices
• General purpose low voltage applications

Procurement Notes

Verify the specific ordering suffix DR2G corresponds to the SOIC-14 package with tape and reel shipping quantities as defined in the official onsemi documentation. Confirm RoHS compliance and Pb-Free status requirements against project specifications before finalizing procurement orders.

Selection Notes

Select this component when multiple independent comparison functions are required within space-constrained designs. The quad configuration reduces board area compared to using single-channel alternatives. Ensure external pull-up resistors are included in the design due to the open-drain output structure.

Part Context

This part belongs to the LMV3xx series, which serves as the low-voltage counterpart to industry-standard LM339 devices. The series includes single (LMV331), dual (LMV393), and quad (LMV339) variants. The LMV339 specifically addresses applications requiring multiple comparators with low power and small footprint constraints.
