TS7211AILT

Overview

The TS7211AILT is a micropower BiCMOS comparator manufactured by STMicroelectronics, housed in a compact SOT-23-5 surface-mount package. It features rail-to-rail input performance and a push-pull output stage, designed for space-critical applications. The device operates on a single supply voltage ranging from 2.7V to 10V and supports industrial temperature ranges from -40°C to +85°C. Key electrical specifications include a typical supply current of 6µA at 5V, a maximum input bias current of 3pA at 5V, and an input offset voltage of up to 7mV at 5V. The component provides a response time of 0.5µs at 5V and offers robust ESD protection rated at 2kV (HBM) and 200V (MM).

Feature Summary

• Rail-to-rail input capability allows operation across the full supply voltage range.
• Micropower consumption with typical supply current of 6µA at 5V.
• Push-pull output stage eliminates the need for external pull-up resistors.
• High ESD protection ratings ensure reliability in sensitive environments.

Applications

• Space and weight critical electronic designs
• Battery-powered portable devices
• Industrial signal conditioning circuits

Procurement Notes

Verify the specific suffix 'AILT' corresponds to the A-grade specification and tape-and-reel packaging format required for your assembly line. Confirm that the SOT-23-5 footprint matches your PCB layout constraints. Ensure compatibility with your manufacturing equipment for small outline packages. Cross-reference the manufacturer part number with official distributor catalogs to confirm current production status and RoHS compliance before finalizing procurement orders.

Selection Notes

Select this component when low power consumption and rail-to-rail input are primary requirements. The SOT-23-5 package is suitable for high-density board layouts where size is a limiting factor. Consider the 0.5µs response time for moderate-speed applications. Verify that the 2.7V minimum supply voltage aligns with your system's power rails. The push-pull output simplifies interface design compared to open-collector alternatives.

Part Context

The TS7211 belongs to the TS7211 series of micropower comparators from STMicroelectronics. This family utilizes BiCMOS technology to balance low power usage with adequate speed. The device is part of ST's portfolio of analog signal processing components designed for general-purpose comparison tasks in consumer and industrial electronics.
