LM393LVDDFR TI Comparator | TSOT-23-8 | Low Voltage, Open Collector Output

Product Overview

The LM393LVDDFR from Texas Instruments is a low-voltage, low-power dual comparator designed for space-constrained applications. Housed in a TSOT-23-8 package, it operates from a single supply voltage as low as 2.0V up to 5.5V, making it ideal for battery-powered and portable electronics. The device features open-collector outputs that allow wired-AND connections and interface with various logic levels. With a typical supply current of just 200µA per comparator, it minimizes power consumption while maintaining fast response times.
