TS7221AI1LT ST Comparator | SOT-23-5 | Low Power, Rail-to-Rail

Product Overview

The TS7221AI1LT is a single low-power, rail-to-rail input comparator from STMicroelectronics, housed in a compact SOT-23-5 package. It operates from a single supply voltage range of 2.7V to 10V and features a typical supply current of only 20 µA, making it ideal for battery-powered and portable applications. The device offers a push-pull output stage, eliminating the need for an external pull-up resistor, and provides fast response times with a propagation delay of typically 1.3 µs. Its rail-to-rail input capability allows the common-mode input voltage to extend from VSS to VDD, enabling use in low-voltage systems.
