LM339BIRTER TI Comparators | 16-WQFN (3x3) | Quad, Low Power, 2V to 36V

Product Overview

The LM339BIRTER from Texas Instruments is a quad-channel, low-power voltage comparator designed for industrial and automotive applications. It operates from a single supply voltage ranging from 2V to 36V or dual supplies of ±1V to ±18V, with very low supply current (0.4 mA per comparator typical). The device features open-collector outputs that can be connected to various logic levels, making it versatile for interfacing with microcontrollers and other digital systems. Packaged in a compact 16-WQFN (3x3 mm), it is ideal for space-constrained designs.
