TS331CX5

Overview

The TS331CX5 is a single precision voltage comparator manufactured by Taiwan Semiconductor Corporation, housed in an SOT-25 package. It supports both single-supply and split-supply operations with a wide supply range of 2V to 36V for single supply and ±1V to ±18V for split supply. The device features low input offset voltage of ±2mV (typical), low input bias current of 25nA, and very low supply current drain of 0.4mA independent of supply voltage. It offers output voltage compatibility with DTL, ECL, TTL, MOS, and CMOS logic levels.

Feature Summary

• Low power consumption with supply current drain of 0.4mA independent of supply voltage
• High precision performance characterized by low input offset voltage and low input bias current
• Wide operating supply voltage range supporting both single and split supply configurations
• Output voltage compatible with various logic families including DTL, ECL, TTL, MOS, and CMOS

Applications

• Consumer electronics applications requiring ground level sensing
• Automotive electronics systems
• Industrial electronics control circuits

Procurement Notes

Verify the specific suffix 'RFG' indicates halogen-free product status when ordering. Confirm the SOT-25 package type matches your PCB footprint requirements. Ensure the supplier provides official datasheets from Taiwan Semiconductor Corporation to validate electrical specifications against the standard TS331 family parameters.

Selection Notes

Select this component for applications demanding low power operation alongside high precision voltage comparison. The wide common mode range extending to ground level makes it suitable for single-supply designs where signal levels approach zero volts. Consider the SOT-25 package size constraints during layout planning.

Part Context

The TS331 series represents a line of micropower comparators designed for efficiency and accuracy. This specific variant from Taiwan Semiconductor focuses on low offset voltage characteristics while maintaining minimal current draw. It serves as a cost-effective solution for battery-powered devices and general-purpose analog switching tasks.

Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers offering similar SOT-25 packages. Verify that substitute parts maintain comparable input offset voltage and supply current specifications to ensure circuit performance consistency without redesign.
