TSX3702IDT

Overview

The TSX3702IDT is a micropower dual CMOS voltage comparator manufactured by STMicroelectronics. It features a typical supply current of 5 µA per comparator and operates within a wide single supply range of 2.7 V to 16 V or dual supplies from ±1.35 V to ±8 V. The device exhibits an extremely low input bias current of 1 pA typical, high input impedance of 10^12 Ω typical, and a fast response time of 2.7 µs typical for 5 mV overdrive. It includes push-pull outputs, ESD tolerance of 4 kV HBM, and functions over a temperature range of -40°C to +125°C.

Feature Summary

• Micropower CMOS architecture with ultra-low current consumption of 5 µA per comparator
• Push-pull output stage eliminating the need for external pull-up resistors
• High robustness with enhanced ESD tolerance of 4 kV HBM
• Wide input common-mode voltage range that includes ground potential

Applications

• Battery-powered portable devices requiring minimal quiescent current
• Industrial sensor signal conditioning and threshold detection
• Automotive grade applications utilizing SO-8 packaging
• General-purpose voltage monitoring and level shifting circuits

Procurement Notes

Verify the specific ordering suffix IDT confirms the SOIC-8 surface-mount package and tape-and-reel shipping configuration. Confirm RoHS compliance status and ensure the component meets automotive reliability standards if required for the target application environment. Cross-reference datasheet revisions to guarantee parameter consistency.

Selection Notes

Select this component when low power consumption is critical alongside standard speed requirements. It serves as an improved successor to the TS3702, offering lower current draw and better input offset voltage characteristics. Ensure the design accommodates the push-pull output structure which differs from open-collector alternatives like the LM393.
