TS3121AIYLT ST Comparator | SOT-23-5 | 1.6V-5.5V, 1.2µA

Product Overview

The TS3121AIYLT is a high-performance, low-power comparator from STMicroelectronics, designed for precision voltage sensing in space-constrained applications. Housed in a compact SOT-23-5 package, this device operates over a wide supply voltage range of 1.6V to 5.5V, making it ideal for battery-powered and portable electronics. With a typical supply current of only 1.2µA, it offers an excellent balance between speed and power consumption. The open-drain output allows for flexible interfacing with various logic levels, and the device features a push-pull output stage capable of sinking and sourcing current. The TS3121AIYLT is specified over the extended industrial temperature range of -40°C to +125°C, ensuring reliable performance in harsh environments.
