TS393IPT

Overview

The TS393IPT 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 with typical propagation delays around 2.5 μs for a 5 mV overdrive. The input stage offers high impedance with extremely low bias and offset currents of 1 pA typical. The output type is open drain, compatible with various logic families.

Feature Summary

• Micropower CMOS technology enabling extremely low consumption compared to bipolar comparators
• Wide operating voltage range supporting both single and dual supply configurations
• High input impedance with negligible input bias and offset currents
• Pin-to-pin and functionally compatible with the dual bipolar LM393

Applications

• Battery-powered systems requiring minimal quiescent current
• Signal conditioning circuits in low-power environments
• General-purpose voltage monitoring applications
• Window comparator configurations

Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel packaging configuration matches your assembly requirements. Confirm that the component meets RoHS3 compliance standards for your target market regulations. Check the manufacturer's datasheet for the latest package marking details and handling instructions to ensure proper surface-mount installation procedures are followed during manufacturing.

Selection Notes

Select this component when system design demands ultra-low power consumption without sacrificing speed relative to standard bipolar comparators. The open-drain output requires an external pull-up resistor, which must be accounted for in the circuit design. Ensure the application voltage stays within the specified 2.7 V to 16 V range to maintain guaranteed performance parameters and reliability across the industrial temperature range.
