TS3021ICT

Overview

The TS3021ICT is a single-channel general-purpose comparator manufactured by STMicroelectronics, housed in a SC-70-5 surface-mount package. It operates on a single supply voltage ranging from 1.8V to 5V. Key electrical specifications include a maximum propagation delay of 105ns, a typical common-mode rejection ratio (CMRR) of 79dB, and a maximum input offset voltage of 6mV at 5V. The device features push-pull outputs and draws a maximum static current of 90µA. Input bias current is specified at 0.16µA @ 5V. It supports an operating temperature range from -40°C to 125°C.

Feature Summary

• Rail-to-rail inputs allow for full signal swing utilization across the supply range.
• Push-pull output stage provides robust drive capability without requiring external pull-up resistors.
• Micropower consumption design ensures efficient operation in battery-powered applications.
• High ESD tolerance protects the component against electrostatic discharge events.

Applications

• Signal conditioning circuits
• Event detection systems
• Threshold monitoring

Procurement Notes

Verify the specific suffix 'ICT' corresponds to the SC-70-5 package and standard industrial temperature grade (-40°C to 125°C). Confirm that the ordering code matches the required tape-and-reel or cut-tape packaging format. Ensure compatibility with the target PCB footprint for the 5-terminal SOT-353/SC-70-5 outline. Cross-reference the manufacturer's latest datasheet for any potential pinout revisions or moisture sensitivity level updates before finalizing procurement.

Selection Notes

Select this component when a low-profile, single-channel comparator is needed for space-constrained designs. It is suitable for applications requiring rail-to-rail input capability and moderate speed performance under a 1.8V to 5V supply. Consider alternatives like the TS3021ILT if an SOT-23-5 package is preferred instead of SC-70-5. Evaluate the 105ns propagation delay against system timing requirements to ensure adequate response time for the intended signal frequencies.

Part Context

The TS3021ICT belongs to the TS3021 family of high-speed comparators from STMicroelectronics. This family includes variants such as TS3021A and TS3021H, which share similar functional characteristics but may differ in temperature ranges or specific electrical parameters. The TS3021 series is designed for automotive and industrial applications, offering a balance between power consumption and response speed in small surface-mount packages.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided source material for direct replacement. Verify pin-to-pin compatibility with other single-channel comparators in the SC-70-5 package if sourcing from different manufacturers.
