LMV331IDCKT

Overview

The LMV331IDCKT is a single-channel general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features an open collector/open drain output type. The device exhibits a propagation delay of 600 ns maximum, with a typical quiescent current of 150 µA. Input specifications include a maximum input offset voltage of 7 mV at 5 V and a maximum input bias current of 0.25 µA at 5 V. It is housed in a SC-70-5 (SOT-353) surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Single-channel general-purpose analog comparator design
• Open collector and open drain compatible output configuration
• Low power consumption suitable for battery-operated applications

Applications

• Threshold detection circuits
• Voltage monitoring systems
• Simple on/off control logic

Procurement Notes

Verify the specific suffix IDCKT corresponds to the SC-70-5 tape and reel packaging format. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as availability may vary. Ensure the ordering quantity aligns with standard reel sizes if bulk procurement is required.

Selection Notes

Select this component when a low-voltage, single-channel comparator is needed with open-drain outputs. Consider the 600 ns propagation delay and 150 µA supply current against application timing and power constraints. Verify that the SC-70-5 package dimensions fit the PCB layout requirements.

Part Context

This part belongs to the LMV331 series of low-voltage comparators. It shares functional similarities with other members like the LMV331IDBVR but differs in package type. The IDCKT variant specifically denotes the SC-70-5 surface-mount package, distinguishing it from SOT-23-5 or other form factors within the same family.

Replacement Considerations

LMV331IDCKR serves as a direct alternative with identical electrical characteristics but potentially different packaging or manufacturing lot variations. Cross-reference pinouts and thermal performance before substitution.
