LMV331IDCKTG4

Overview

The LMV331IDCKTG4 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. Key electrical parameters include a maximum propagation delay of 600 ns, a maximum input offset voltage of 7 mV at 5 V, and a maximum input bias current of 250 nA at 5 V. The device draws a maximum quiescent current of 150 µA and supports a typical output current of 84 mA at 5 V. It is housed in a SC-70-5 (SOT-353) surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Single-channel general-purpose analog comparator design
• Low-voltage operation capability from 2.7 V to 5.5 V
• Open collector or open drain output configuration
• Compact SC-70-5 surface-mount packaging

Applications

• Battery-powered systems requiring low supply voltage
• Threshold detection circuits
• Voltage monitoring applications
• General-purpose signal comparison tasks

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per Texas Instruments documentation. Confirm the SC-70-5 package marking and pinout alignment with the official datasheet before integration. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when a single comparator with low power consumption and small footprint is required. The open-drain output allows for flexible interfacing with various logic levels through external pull-up resistors. Consider the 600 ns propagation delay for timing-sensitive designs. Verify that the 2.7 V minimum supply voltage aligns with the system's power budget and battery discharge characteristics.

Part Context

This part belongs to the LMV331 series of low-voltage comparators from Texas Instruments. The 'IDCKT' designation specifies the industrial temperature grade (-40°C to +85°C), the SC-70-5 package, and tape-and-reel packaging. The 'G4' suffix typically denotes Green/RoHS-compliant manufacturing. It serves as a compact alternative to larger packages while maintaining comparable electrical performance for general-purpose applications.

Replacement Considerations

LMV331IDCKT: Direct functional equivalent with identical specifications but potentially different packaging suffix or compliance status. LMV331IDBVR: Same core comparator in a SOT-23-5 package, requiring PCB layout adjustment. LMV393: Dual-channel alternative offering two comparators in one package, suitable if additional channels are needed.
