TS3021IYCT

Overview

The TS3021IYCT is a single-channel high-speed analog comparator manufactured by STMicroelectronics, housed in a compact SC-70-5 surface-mount package. It operates on a single supply voltage ranging from 1.8 V to 5 V and features rail-to-rail inputs for maximum dynamic range. The device delivers a typical propagation delay of 38 ns with a low quiescent current consumption of 73 µA. It utilizes push-pull outputs capable of sourcing or sinking up to 26 mA. The component is rated for an extended operating temperature range from -40 °C to +125 °C and includes high ESD protection ratings.

Feature Summary

• Rail-to-rail input capability allows signal detection across the full supply voltage range.
• Push-pull output stage provides robust drive capability without requiring external pull-up resistors.
• High electromagnetic compatibility through superior ESD tolerance and latch-up immunity.
• Optimized power efficiency offering a favorable ratio between speed and current consumption.

Applications

• Automotive sensor interface circuits
• Overcurrent protection systems
• Industrial controller logic interfaces

Procurement Notes

Verify the specific suffix 'IYCT' against official datasheets to confirm the SC-70-5 package and industrial temperature grade. Ensure the ordering code matches the required tape-and-reel quantity. Cross-reference the manufacturer's part number database to validate active status and pinout configuration before finalizing procurement specifications.

Selection Notes

Select this component when space constraints require a small SC-70-5 footprint alongside high-speed switching requirements. It is suitable for applications demanding rail-to-rail input performance at low supply voltages. Consider the 73 µA current draw for battery-powered designs where power efficiency is critical alongside response time.

Part Context

This device belongs to the TS3021 family of single comparators designed for high-speed and low-power applications. The family includes variants such as TS3021ILT in SOT-23-5 packages. These components are engineered to provide automotive-grade reliability within compact form factors, supporting integration into modern electronic systems requiring precise voltage threshold detection.

Replacement Considerations

Direct substitutes include other members of the TS3021 family, such as TS3021ICT or TS3021AILT, provided the package type and electrical characteristics align with the design requirements. Verify pin compatibility and thermal performance when swapping between different package options within the same series.
