LM339PWRG4 TI Comparator | 14-TSSOP | Low Power, Quad Channel

Product Overview

The LM339PWRG4 is a quad-channel, low-power voltage comparator from Texas Instruments (TI). It is designed for applications requiring multiple comparators in a compact 14-TSSOP package. The device operates from a single power supply over a wide voltage range of 2V to 36V (or ±1V to ±18V for dual supplies) and features low supply current drain (0.8 mA typical) independent of supply voltage. The LM339PWRG4 has open-collector outputs that can be connected to other open-collector outputs to achieve wired-AND logic. It is characterized for operation from 0°C to 70°C.
