LM397MF/NOPB TI Comparator | SOT-23-5 | Single, Open-Collector, 2V to 36V

Product Overview

The LM397MF/NOPB is a single, low-power, open-collector voltage comparator from Texas Instruments. It is designed for general-purpose applications requiring a wide supply voltage range from 2V to 36V (or ±1V to ±18V dual supplies). The device features low supply current (0.4 mA typical), fast response time (1.3 µs typical), and an open-collector output that allows wired-OR connections. Housed in a compact SOT-23-5 package, it is ideal for space-constrained designs.
