TS374CDT

Overview

The TS374CDT is a quad low-power analog comparator manufactured by STMicroelectronics, housed in a 14-pin SOIC surface-mount package. It operates within a supply voltage range of 3 V to 16 V with a typical quiescent current of 250 uA. The device features an open-drain output capable of sourcing 20 mA per channel and offers a response time of 600 ns. Key electrical characteristics include a maximum input offset voltage of 10 mV and input bias currents as low as 100 pA to 150 pA. It functions reliably across a temperature range of 0°C to +70°C without a shutdown mode.

Feature Summary

• Quad configuration providing four independent general-purpose comparison channels in a single compact package.
• Low power consumption design suitable for battery-operated applications with minimal quiescent current draw.
• Open-drain output structure allowing flexible interfacing with various logic families and pull-up configurations.

Applications

• General purpose signal conditioning and threshold detection circuits
• Battery-powered portable devices requiring low standby current
• Industrial control systems utilizing standard voltage levels

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure the correct tape-and-reel packaging variant matches your assembly requirements. Confirm that the SOIC-14 footprint aligns with your PCB layout specifications. Ensure the industrial temperature range meets your operational environment standards before finalizing procurement.

Selection Notes

Select this component when multiple independent comparators are needed in a space-constrained design. The open-drain output requires external pull-up resistors, which must be accounted for in the circuit design. Consider the 600 ns propagation delay for high-speed applications; faster alternatives may be necessary if sub-nanosecond response times are critical.

Part Context

This part belongs to the TS374 series of low-power quad comparators from STMicroelectronics. It serves as a general-purpose solution for voltage monitoring and switching applications. The device integrates four comparators into a single SOIC-14 package, offering a cost-effective alternative to using discrete components or multiple dual-comparator ICs.

Replacement Considerations

Check for pin-compatible alternatives such as the LM339 or LM393 series, ensuring output type and supply voltage ranges match. Verify that any substitute maintains the required low-power characteristics and open-drain output configuration for direct replacement in existing designs.
