TS3022IYST

Overview

The TS3022IYST is a dual high-speed comparator from STMicroelectronics, featuring rail-to-rail inputs and push-pull outputs. It operates on a supply voltage range of 1.8V to 5V with micropower consumption as low as 73 µA per comparator. The device offers a propagation delay of 38 ns and input offset voltage of 6mV at 5V. It supports an operating temperature range from -40°C to +125°C and includes ESD tolerance of 5 kV HBM. Packaged in an 8-MiniSO surface-mount format, it provides excellent power consumption versus response time ratio.

Feature Summary

• Rail-to-rail input capability for wide signal compatibility
• High-speed response with low propagation delay
• Micropower consumption suitable for battery-operated applications
• Push-pull output configuration

Applications

• Battery-powered systems requiring low current draw
• High-speed signal processing circuits
• Threshold detection and timing applications
• Portable electronic devices

Procurement Notes

Verify the specific suffix 'IYST' corresponds to the MiniSO-8 package and industrial temperature grade (-40°C to +125°C) when ordering. Confirm that the rail-to-rail input specification aligns with your system's common-mode voltage requirements. Ensure proper handling procedures are followed due to the small surface-mount package type.

Selection Notes

Select this component when both high speed and low power consumption are critical design constraints. The rail-to-rail input feature allows operation closer to supply rails compared to standard comparators. Consider the 8-pin MiniSO package dimensions for PCB layout space limitations. Verify that the 6mV input offset voltage meets your precision requirements.

Part Context

This part belongs to the TS3022 series of dual comparators designed by STMicroelectronics. The series emphasizes the balance between speed and power efficiency. Other variants in the family may offer different package options or single-channel configurations like the TS3021.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that match the 8-MiniSO footprint and electrical specifications. Verify if other dual comparators with similar propagation delay and supply voltage ranges are available.
