TLV1821LDBVR TI Comparator | SOT-23-5 | Low Power, Open-Drain Output

Product Overview

The TLV1821LDBVR is a single-channel, low-power comparator from Texas Instruments, housed in a compact SOT-23-5 package. It features an open-drain output and operates over a wide supply voltage range of 1.8V to 5.5V, making it ideal for battery-powered and portable applications. With a typical quiescent current of only 600 nA, it is optimized for low-power consumption while maintaining a propagation delay of 4 µs. The device includes internal hysteresis for clean switching and is specified over the extended industrial temperature range of -40°C to +125°C.
