TS374CN

Overview

The TS374CN is a quad CMOS voltage comparator manufactured by STMicroelectronics. It features four independent precision comparators designed for single or dual supply operation. The device utilizes silicon line MOS technology to achieve an optimal consumption-speed ratio, making it suitable for low-power applications. Key electrical characteristics include a typical response time of 200ns for TTL level input steps and a high input impedance of 10^12 ohms. It operates within a wide single supply range of 3V to 16V or dual supplies from ±1.5V to ±8V. The input common-mode voltage range includes ground, and the output is compatible with TTL, MOS, and CMOS logic families.

Procurement Notes

Verify the specific suffix 'CN' against official STMicroelectronics documentation to confirm package type and temperature grade. Ensure the ordering part number matches the required industrial specifications. Cross-reference datasheet revisions to confirm pinout and electrical parameter consistency before integration into design files.

Selection Notes

Select this component when multiple independent comparison functions are required in a space-constrained design. The CMOS architecture offers high input impedance and low bias current, suitable for sensitive signal sources. Verify that the 200ns response time meets the system's timing requirements and that the output drive capability aligns with the connected load logic family.

Part Context

The TS374 belongs to a family of quad comparators utilizing CMOS technology. It serves as a general-purpose analog comparator solution for consumer and industrial electronics. The device provides a cost-effective alternative to bipolar comparators where lower power dissipation and higher input impedance are prioritized over ultra-fast switching speeds.

Replacement Considerations

Check for direct pin-compatible alternatives such as the LM393 or LM339 if bipolar supply flexibility is not required. Verify that substitute devices meet the same input offset voltage and supply current specifications to maintain circuit performance without redesign.
