Overview
The TS374CD is a low-power quad voltage comparator manufactured by STMicroelectronics. It features four independent channels housed in a SOIC-14 surface-mount package. The device operates within a supply voltage range of 3 V to 16 V and draws a typical operating current of 250 uA. Key electrical specifications include a response time of 600 ns, an input offset voltage of 10 mV, and an input bias current of 150 pA. Each channel provides an open-drain output capable of sourcing up to 20 mA. The component is rated for operation between 0 C and +70 C with a maximum power dissipation of 830 mW.
Feature Summary
- Quad configuration providing four independent general-purpose comparison functions
- Low-power design optimized for battery-operated applications
- Open-drain output stage allowing flexible interfacing with various logic families
Applications
- General purpose signal conditioning circuits
- Threshold detection systems
- Simple analog-to-digital conversion interfaces
Procurement Notes
Verify the specific suffix against the official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the selected package variant matches the intended PCB footprint requirements. Confirm that the operating temperature range aligns with the final system environment constraints before procurement.
Selection Notes
Select this component when multiple independent comparators are required in a compact form factor. The low quiescent current makes it suitable for portable devices where power efficiency is critical. Verify that the open-drain output architecture meets the pull-up resistor requirements of the downstream circuitry.
Part Context
This part belongs to the TS374 series of analog comparators from STMicroelectronics. The series is designed to offer high performance at low cost for general-purpose applications. The TS374CD specifically denotes the quad version in a standard small-outline integrated circuit package, distinguishing it from dual or single-channel variants within the same family.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Ensure any replacement maintains the quad channel count, SOIC-14 package, and compatible supply voltage ranges.
