TS393IN

Overview

The TS393IN is a micropower CMOS dual voltage comparator in an 8-pin DIP package. It operates from a single supply of 2.7 V to 16 V or dual supplies of ±1.35 V to ±8 V. The device features extremely low supply current, typically 9 µA per comparator. Input bias and offset currents are typically 1 pA. The input common-mode voltage range includes ground. Response time is typically 2.5 µs for a 5 mV overdrive. Operating temperature range is -40 °C to +125 °C.

Feature Summary

• Extremely low power consumption with typical supply current of 9 µA per comparator
• High input impedance with extremely low input bias and offset currents
• Wide single or dual supply voltage operation capability
• Input common-mode voltage range extends to include ground potential

Applications

• Battery-powered measurement systems requiring minimal quiescent current
• Signal conditioning circuits utilizing wide dynamic voltage ranges
• Low-power window comparator configurations
• General-purpose differential voltage comparison tasks

Procurement Notes

Verify the specific ordering code matches the required industrial temperature grade (-40 °C to +125 °C) and plastic DIP-8 packaging configuration. Confirm that the component meets the necessary environmental compliance standards defined by the manufacturer's ECOPACK specifications before finalizing procurement decisions.

Selection Notes

Select this component when system design requires pin-to-pin compatibility with standard bipolar LM393 devices while demanding significantly lower power dissipation. The high input impedance makes it suitable for applications involving high-impedance signal sources where loading effects must be minimized during voltage threshold detection.

Part Context

This part belongs to the TS393 family of micropower CMOS dual voltage comparators manufactured by STMicroelectronics. It serves as a low-power alternative to traditional bipolar comparators, offering similar response times but with drastically reduced supply current requirements across the specified operating temperature range.

Replacement Considerations

Functionally compatible with the dual bipolar LM393 device. The TS3702 offers similar performance with a push-pull CMOS output stage.
