LMV331/393/339 are low voltage (2.7-5V) versions of the dual and quad comparators, LM393/339, which are specified at 5-30V. The LMV331 is the single version, which is available in space saving SC70-5 and SOT23-5 packages. SC70-5 is approximately half the size of SOT23-5. The LMV393 is available in 8-pin SOIC and 8-pin MSOP. The LMV339 is available in 14-pin SOIC and 14-pin TSSOP. The LMV331/393/339 is the most cost-effective solution where space, low voltage, low power and price are the primary specification in circuit design for portable consumer products. They offer specifications that meet or exceed the familiar LM393/339 at a fraction of the supply current. The chips are built with National's advanced Submicron Silicon-Gate BiCMOS process. The LMV331/393/339 have bipolar input and output stages for improved noise performance.
This document is a technical datasheet for the National Semiconductor LMV331 (single), LMV393 (dual), and LMV339 (quad) general-purpose low voltage comparators. These devices are designed as low-voltage versions of the popular LM393/339 series, specified for operation between 2.7V and 5V supply voltages.
