TS3011IYLT

Overview

The TS3011IYLT is a single-channel, high-speed rail-to-rail analog comparator manufactured by STMicroelectronics. It operates within a supply voltage range of 2.2 V to 5 V and supports a wide operating temperature range from -40 °C to +125 °C. The device features a propagation delay of 8 ns and a typical quiescent current consumption of 470 μA at 5 V. It utilizes a push-pull output stage capable of sourcing or sinking up to 18 mA per channel. The component is housed in a compact SOT-23-5 surface-mount package and holds AEC-Q101 automotive qualification.

Feature Summary

• High-speed response with an 8 ns propagation delay for rapid signal processing
• Rail-to-rail input capability allowing operation across the full supply voltage range
• Push-pull output configuration providing robust drive strength without external pull-up resistors
• Automotive-grade reliability certified under AEC-Q101 standards

Applications

• Automotive sensor signal conditioning and threshold detection
• Overcurrent protection circuits in power management systems
• High-speed data acquisition systems requiring fast voltage comparison
• Industrial control logic interfaces

Procurement Notes

Verify the specific suffix 'LT' against the official STMicroelectronics datasheet to confirm it denotes the SOT-23-5 package variant. Ensure the order includes the correct tape-and-reel quantity specified in the manufacturer's documentation. Confirm that the AEC-Q101 qualification status meets the specific reliability requirements of the target application before finalizing procurement.

Selection Notes

Select this component when system design requires a balance between high switching speed and moderate power consumption. The rail-to-rail input feature simplifies interface design with sensors operating near ground or supply rails. The push-pull output eliminates the need for external pull-up components, reducing bill-of-materials count. Verify that the 470 μA typical current draw aligns with the thermal and power budget constraints of the end product.

Part Context

The TS3011 belongs to STMicroelectronics' portfolio of high-performance analog comparators designed for space-constrained applications. This series emphasizes low power consumption relative to its speed, making it suitable for battery-operated or thermally sensitive environments. The inclusion of automotive qualification expands its utility beyond consumer electronics into critical safety and infotainment systems.

Replacement Considerations

Consult the official STMicroelectronics replacement guide for direct pin-compatible alternatives. Verify that any substitute maintains the 8 ns propagation delay and 2.2 V minimum supply voltage. Ensure the replacement device offers comparable ESD protection levels and operates within the same -40 °C to +125 °C temperature range.
