LMV393IDDURG4

Overview

The LMV393IDDURG4 is a quad general-purpose low-voltage comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and consumes a typical quiescent current of 20 µA per channel. The device features an open-drain output configuration with a propagation delay of 200 ns. It supports input common-mode voltages that include ground and provides an output saturation voltage as low as 10 mV. The component is housed in an 8-pin VSSOP package and is rated for operation across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Quad-channel architecture providing four independent comparators in a single compact package
• Low-voltage operation capability supporting systems powered between 2.7 V and 5.5 V
• Ultra-low power consumption design suitable for battery-operated applications
• Open-drain outputs allowing flexible interfacing with various logic families

Applications

• Battery-powered portable electronics requiring minimal standby current
• Threshold detection circuits in low-voltage monitoring systems
• Signal conditioning stages for microcontroller input interfaces
• Window comparator configurations for voltage level supervision

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS standards during sourcing. Confirm the 'IDDR' package designation matches the required VSSOP-8 footprint and pin pitch for PCB layout. Ensure the manufacturer datasheet is consulted for the latest moisture sensitivity level and reflow soldering profile recommendations before assembly.

Selection Notes

Select this component when a system requires multiple comparison functions within a constrained space and low power budget. The quad configuration reduces board area compared to using individual dual or single comparators. Verify that the open-drain output requirement aligns with the pull-up resistor strategy needed for the target logic voltage levels.

Part Context

This part belongs to the LMV3xx series, which serves as the low-voltage counterpart to the industry-standard LM339/LM393 family. While maintaining similar functional characteristics, the LMV3xx series offers significantly reduced current consumption and compatibility with lower supply voltages. This makes it ideal for modern portable devices where power efficiency and small form factors are critical design constraints.

Replacement Considerations

LMV393IDDR is the non-RoHS compliant predecessor. LMV393IDDRG4 is the direct equivalent with identical electrical specifications but updated manufacturing compliance.
