LMC7221BIM5/NOPB TI Comparator | SOT-23-5 | Low Power, Open Drain Output

Product Overview

The LMC7221BIM5/NOPB from Texas Instruments is a low-power, high-performance comparator in a compact SOT-23-5 package. It features an open-drain output, making it ideal for level shifting and wired-OR configurations. With a supply voltage range of 2.7V to 15V and ultra-low supply current of 0.4 µA (typical), it is optimized for battery-powered and portable applications. The device offers rail-to-rail input common-mode voltage range and fast propagation delay of 4 µs (typical) at 5V.
