TS374IN

Overview

The TS374IN is a quad low-power voltage comparator manufactured by STMicroelectronics. It features four independent channels within a single package, designed for general-purpose analog signal processing tasks. The device operates with a supply voltage range from 3 V to 16 V and draws a typical operating current of 250 uA per channel. It utilizes an open-drain output configuration capable of sourcing up to 20 mA. Key electrical specifications include a response time of 600 ns, an input offset voltage of 10 mV, and an input bias current of 300 pA. The component supports operation across a temperature range of -40 C to +125 C and is housed in a DIP-14 package.

Feature Summary

• Quad-channel architecture providing four independent comparison functions in a compact form factor
• Low power consumption design suitable for battery-operated or energy-efficient applications
• Open-drain outputs allow flexible interfacing with various logic families through external pull-up resistors
• Wide supply voltage compatibility enabling use in diverse system environments

Applications

• General-purpose analog signal conditioning circuits
• Threshold detection systems requiring precise voltage level monitoring
• Low-power instrumentation interfaces
• Simple oscillator or timing circuit generation

Procurement Notes

Verify the specific suffix 'IN' against the manufacturer's official datasheet to confirm the package type and pinout configuration. Ensure that the open-drain output requirements align with the target circuit design, as this necessitates external pull-up components for proper logic level translation. Confirm compliance with relevant environmental standards such as RoHS if required for the final assembly process.

Selection Notes

Select this component when multiple independent comparators are needed without consuming excessive board space. The low quiescent current makes it appropriate for portable devices where power efficiency is critical. Consider the open-drain output nature when designing the load interface, ensuring that the external pull-up voltage does not exceed the maximum ratings. The wide operating temperature range supports deployment in industrial or automotive environments.

Part Context

The TS374 series belongs to STMicroelectronics' portfolio of analog comparators, offering a balance between performance and power efficiency. This family is designed to replace older discrete transistor solutions or operational amplifiers used in comparator configurations. The quad configuration provides a cost-effective solution for multi-channel sensing applications, reducing component count and simplifying PCB layout compared to using individual single-channel units.

Replacement Considerations

Check for direct pin-compatible alternatives within the same comparator family or from other manufacturers offering similar quad low-power specifications. Verify that any substitute maintains the same open-drain output structure and supply voltage range to ensure circuit compatibility without redesign.
