TS3021IYLT

Overview

The TS3021IYLT is a single-channel analog comparator manufactured by STMicroelectronics, housed in an SOT-23-5 surface-mount package. It operates on a single supply voltage ranging from 1.8V to 5V with a maximum quiescent current of 90µA. The device features rail-to-rail inputs and push-pull outputs, ensuring compatibility with various logic families. Key electrical specifications include a maximum propagation delay of 105ns, an input offset voltage of up to 6mV at 5V, and an input bias current of 0.16µA. It supports a wide operating temperature range from -40°C to +125°C and offers high ESD protection.

Feature Summary

• Rail-to-rail input capability for extended common-mode voltage range
• Push-pull output stage providing direct interface to digital logic
• Low power consumption suitable for battery-operated applications
• High electromagnetic interference immunity with robust ESD tolerance

Applications

• Threshold detection circuits
• Voltage monitoring systems
• Logic level shifting interfaces
• Over-voltage/under-voltage protection

Procurement Notes

Verify the specific suffix 'IYLT' against the official datasheet to confirm the industrial temperature grade (-40°C to +125°C) and tape-and-reel packaging configuration. Ensure the ordering part number matches the required pinout and performance characteristics defined in the STMicroelectronics product specification sheet before finalizing procurement.

Selection Notes

Select this component when a low-power, high-speed comparator with rail-to-rail inputs is required in a compact SOT-23-5 footprint. It is suitable for designs needing push-pull outputs to drive digital loads directly without additional pull-up resistors. Consider the 105ns propagation delay and 90µA supply current limits to ensure they meet the system's timing and power budget constraints.

Part Context

The TS3021 series represents STMicroelectronics' line of micropower comparators designed for general-purpose applications. The TS3021IYLT variant specifically denotes the industrial temperature range version packaged in a reel format. This series is engineered to offer an optimal balance between speed and power efficiency, making it a standard choice for portable electronics and signal conditioning tasks.

Replacement Considerations

TS3021AILT: Same family member with potentially different temperature or packaging specs; verify suffix details. TS3021ILT: Alternative within the same series; confirm if industrial grade requirements are met.
