TS334IYPT

Overview

The TS334IYPT is a single-channel micropower low-voltage analog comparator manufactured by STMicroelectronics. It operates within a supply voltage range of 1.6 V to 5 V and features rail-to-rail inputs, making it suitable for low-voltage applications. The device exhibits a typical current consumption of 20 μA and an open-drain output type with a propagation delay of 210 ns. It is housed in a TSSOP-14 surface-mount package and supports an operating temperature range from -40 °C to +125 °C. The component is AEC-Q100 qualified for automotive reliability.

Feature Summary

• Rail-to-rail input capability enables accurate signal detection in low-voltage environments
• Micropower design ensures minimal energy consumption during operation
• Automotive qualification provides enhanced reliability for vehicle electronics

Applications

• Low-voltage battery monitoring systems
• Automotive sensor interface circuits
• Portable electronic device protection

Procurement Notes

Verify the specific suffix 'YPT' corresponds to the TSSOP-14 package and reel/cut-tape packaging configuration as listed in official distributor catalogs. Confirm that the AEC-Q100 qualification status aligns with your system's automotive grade requirements before finalizing procurement decisions.

Selection Notes

Select this component when a single comparator channel is required for low-power, low-voltage applications. The rail-to-rail input feature is critical for maximizing dynamic range near ground and supply rails. Ensure the open-drain output architecture matches the pull-up resistor requirements of the downstream logic circuitry.

Part Context

This part belongs to the TS33x family of micropower comparators, which includes single (TS331), dual (TS332), and quad (TS334) variants. The family shares common electrical characteristics such as low supply voltage operation and high input impedance, allowing for flexible design scaling across different channel count requirements while maintaining consistent performance profiles.

Replacement Considerations

Cross-reference with other single-channel comparators in the TS33x series if pin compatibility differs. Verify that alternative devices maintain the same 1.6 V minimum supply voltage and open-drain output structure to ensure direct functional substitution without circuit modification.
