LM393LVQDRQ1 TI Low-Voltage Comparator | 8-SOIC | 2.7V-5.5V, Open-Drain Output

Product Overview

The LM393LVQDRQ1 is a low-voltage, low-power dual comparator from Texas Instruments, designed for automotive and industrial applications. It operates from a single supply voltage of 2.7V to 5.5V, making it ideal for battery-powered systems. The device features open-drain outputs that allow for wired-AND connections and interface with various logic families. Housed in an 8-pin SOIC package, it offers excellent performance with low supply current (0.4 mA typical) and fast response time (1.3 μs typical).
