TS3121ILT ST Comparator | SOT-23-5 | Rail-to-Rail, Low Power

Product Overview

The TS3121ILT from STMicroelectronics is a single, low-power, rail-to-rail input comparator in a compact SOT-23-5 package. It operates from a single supply voltage range of 1.8V to 5.5V, making it ideal for battery-powered and portable applications. The device features a push-pull output stage, eliminating the need for an external pull-up resistor. With a typical supply current of only 20 µA and a propagation delay of 600 ns, it balances low power consumption with adequate speed for many sensing and monitoring tasks.
