The LMV393 and LMV339 devices are low-voltage (2.7V to 5.5V) versions of the dual and quad comparators, LM393 and LM339, which operate from 5V to 30V. The LMV331 is the single-comparator version.

The LMV331, LMV339, and LMV393 are the most cost-effective devices for applications where low-voltage operation, low power, and space saving are the primary specifications in circuit design for portable consumer products. These devices offer specifications that meet or exceed the familiar LM339 and LM393 devices at a fraction of the supply current.
