NSC LP339M  Ultra-Low Power Quad Comparator  SO14

Manufactured by National Semiconductor - SO14 SMD Package

DESCRIPTION

The LP339 consists of four independent voltage comparators designed specifically to operate from a single power supply and draw typically 60 μA of power supply drain current over a wide range of power supply voltages. Operation from split supplies is also possible and the ultra-low power supply drain current is independent of the power supply voltage.

These comparators also feature a common-mode range which includes ground, even when operated from a single supply.

The LP339 was specifically designed to interface with the CMOS logic family. The ultra-low supply current makes the LP339 valuable in battery powered applications.
