TS332IYDT

Overview

The TS332IYDT is a dual micropower low-voltage comparator manufactured by STMicroelectronics. It operates with a supply voltage ranging from 1.6 V to 5 V and features rail-to-rail inputs. The device consumes a typical current of 20 μA per channel and exhibits a propagation delay of 210 ns. It utilizes an open-drain output configuration and is housed in an SO-8 surface-mount package. The component supports an industrial temperature range from -40 °C to +125 °C.

Feature Summary

• Rail-to-rail input capability for low-voltage signal compatibility
• Micropower operation with low current consumption suitable for battery applications
• Open-drain output structure allowing flexible logic interfacing

Applications

• Low-voltage threshold detection circuits
• Battery-powered portable devices
• Industrial control systems requiring wide temperature stability

Procurement Notes

Verify the specific suffix 'IYDT' against the official datasheet to confirm the SO-8 package, industrial grade temperature rating, and tape-and-reel packaging format. Ensure design compliance with the specified 1.6 V to 5 V supply constraints and open-drain output requirements before finalizing procurement specifications.

Selection Notes

Select this component when dual-channel comparison is required within strict power budgets. The rail-to-rail input feature simplifies interface design for signals swinging near ground or supply rails. Consider the open-drain output requirement for pull-up resistor selection and logic level compatibility in the target application circuit.

Part Context

This part belongs to the TS33x family of comparators, which includes single (TS331), dual (TS332), and quad (TS334) variants. The family shares common electrical characteristics such as micropower consumption and low-voltage operation, offering designers scalable channel counts while maintaining consistent performance parameters across the series.

Replacement Considerations

Cross-reference with other members of the TS33x family, such as TS331 or TS334, if channel count adjustments are needed. Verify pinout compatibility and electrical parameter alignment with alternative dual comparators from other manufacturers before substitution.
