TS393IYDT

Overview

The TS393IYDT is a micropower CMOS dual voltage comparator manufactured by STMicroelectronics. It features an extremely low supply current of typically 9 μA per comparator, which is significantly lower than bipolar equivalents. The device operates within a wide single supply range of 2.7 V to 16 V or dual supplies from ±1.35 V to ±8 V. It provides fast response times and includes input common-mode voltage range that extends to ground. The component is housed in an 8-SOIC surface-mount package and is qualified under the AEC-Q100 standard for automotive applications.

Feature Summary

• Extremely low power consumption with typical supply current of 9 μA per comparator
• Wide operating voltage range supporting both single and dual supply configurations
• CMOS input architecture providing high input impedance and ground-referenced common-mode voltage
• Automotive grade qualification ensuring reliability in demanding environments

Applications

• Battery-powered systems requiring minimal quiescent current
• Automotive electronic circuits subject to AEC-Q100 standards
• General-purpose voltage monitoring and threshold detection
• Signal conditioning in low-power industrial instrumentation

Procurement Notes

Verify the specific ordering suffix matches the required package variant and tape/reel configuration. Confirm AEC-Q100 automotive qualification status if the application demands it. Check RoHS compliance documentation against regional regulatory requirements. Ensure the supplier source aligns with authorized distribution channels to guarantee part authenticity and traceability.

Selection Notes

Select this component when low static power consumption is critical compared to bipolar comparators. The CMOS input stage offers higher impedance than bipolar alternatives. Verify that the open-drain output type suits the pull-up requirements of the target circuit. Consider the 8-SOIC package dimensions for PCB layout constraints.

Part Context

This part belongs to the TS393 family of micropower dual voltage comparators. It serves as a CMOS alternative to traditional bipolar devices like the LM393, offering similar pinouts but with reduced power usage. The series is designed for applications where battery life and low heat dissipation are primary design constraints.

Replacement Considerations

Direct substitutes include the NCV2393DR2G from onsemi. Verify electrical parameter compatibility and package footprint alignment before substitution.
