TSX339IDT

Overview

The TSX339IDT is a micropower CMOS quad voltage comparator manufactured by STMicroelectronics. It features four independent comparators with open-drain outputs, designed for low current consumption of 5 µA typical per comparator. The device operates on a wide single supply range from 2.7 V to 16 V or dual supplies (±1.35 V to ±8 V). Key electrical characteristics include an extremely low input bias current of 1 pA typical, high input impedance of 10^12 Ω typical, and fast response time of 2 µs typical for 5 mV overdrive. It offers enhanced ESD tolerance of 4 kV HBM and 200 V MM. The component is fully specified over a temperature range of -40 °C to 125 °C and is housed in a 14-SOIC package.

Feature Summary

• Micropower operation with very low current consumption per comparator
• Wide single and dual supply voltage ranges
• Enhanced electrostatic discharge (ESD) protection capabilities
• Pin-to-pin and functionally compatible with the TS339 series

Applications

• Automotive systems
• Industrial applications

Procurement Notes

Verify the specific order code against the official datasheet to ensure correct package type and packing method. Confirm that the SO14 tape and reel configuration matches the intended manufacturing process requirements. Check environmental compliance specifications such as ECOPACK grades if required by the project standards. Ensure the operating temperature range aligns with the system's thermal design constraints.

Selection Notes

Select this component when low power consumption is critical alongside standard comparator functionality. It serves as a direct replacement for the TS339 in existing designs without requiring schematic changes. Consider the QFN16 3x3 package option if board space is limited, though the IDT suffix specifically denotes the SO14 package. Evaluate the open-drain output requirement for pull-up resistor integration in the target circuit design.

Part Context

The TSX339 represents an improved version of the TS339 quad CMOS comparator family. It offers lower current consumption, better input offset voltage performance, and enhanced ESD tolerance compared to its predecessor. The device is available in multiple packages including SO14, TSSOP14, and QFN16 3x3. The TSX339IDT specifically refers to the SO14 package variant supplied in tape and reel format.

Replacement Considerations

The TSX339 is pin-to-pin and functionally compatible with the TS339. Designers can replace TS339 components with TSX339 parts directly in most applications due to identical pinouts and similar electrical characteristics.
