TS3021HIYLT

Overview

The TS3021HIYLT is a single-channel high-speed comparator manufactured by STMicroelectronics, designed for surface-mount applications in SOT-23-5 packages. It operates on a single supply voltage ranging from 1.8V to 5V and features rail-to-rail inputs with push-pull outputs. The device offers a typical propagation delay of 38ns and low quiescent current consumption of 73µA. It supports an extended operating temperature range from -40°C to +150°C and holds AEC-Q100 automotive qualification.

Feature Summary

• Automotive-grade reliability with AEC-Q100 certification for harsh environments
• High-speed performance with rail-to-rail input capability
• Low power consumption optimized for battery-operated systems
• Robust protection including high ESD tolerance and latch-up immunity

Applications

• Automotive electronic control units and sensor interfaces
• Portable consumer electronics requiring low power operation
• Industrial signal processing and threshold detection circuits
• Battery-powered devices and mobile communication equipment

Procurement Notes

Verify the specific suffix 'HIYLT' against official STMicroelectronics documentation to confirm automotive grade status and package variant. Ensure compatibility with design-in requirements regarding thermal management and supply voltage ranges. Cross-reference ordering information with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when automotive qualification and wide temperature operation are critical. The rail-to-rail input feature simplifies interface design with various sensors. Consider the SOT-23-5 package size for space-constrained PCB layouts. Evaluate the trade-off between the 38ns propagation delay and 73µA current consumption for specific application needs.

Part Context

Part of the TS3021 family of high-speed comparators. The HIYLT suffix denotes specific automotive-grade specifications and packaging. Shares core electrical characteristics with other TS3021 variants but differs in qualification standards and potentially minor parameter tolerances defined by the manufacturer.

Replacement Considerations

Check for direct substitutes within the TS3021 series such as TS3021ILT or TS3021IYLT if automotive qualification is not required. Verify pinout compatibility and electrical parameters before substituting with generic comparators.
