LM393N/NOPB TI Comparator | 8-PDIP | Dual, Low Power, 1.3μs Response

Product Overview

The LM393N/NOPB is a dual low-power voltage comparator from Texas Instruments, designed for applications requiring high precision and low power consumption. Housed in an 8-pin PDIP package, it operates from a single power supply over a wide voltage range of 2V to 36V (or ±1V to ±18V for dual supplies). The device features open-collector outputs, allowing wired-AND connections, and offers a fast response time of 1.3μs typical. With a low supply current of 0.4mA per comparator at 5V, it is ideal for battery-powered and portable equipment.
