LM293DRE4 TI Low-Power Dual Comparator | 8-SOIC | 2-36V Supply, Open-Collector Output

Product Overview

The LM293DRE4 from Texas Instruments is a low-power, dual-channel voltage comparator designed for a wide range of applications. It operates from a single power supply over a wide voltage range of 2V to 36V (or dual supplies of ±1V to ±18V) and features low supply current (0.4 mA per comparator at 5V). The open-collector output allows wired-AND connections and interfacing with various logic families. The device is offered in an 8-pin SOIC package, making it suitable for space-constrained designs.
