LMV339IDR

Overview

The LMV339IDR is a quad low-voltage analog comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates within a supply voltage range of 2.7 V to 5.5 V and features an open collector output type. Key electrical parameters include a maximum propagation delay of 200 ns, a typical operating supply current of 75 uA, and a maximum input offset voltage of 7 mV. The device supports a common-mode voltage down to -100 mV and delivers up to 10 mA per channel output current. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Quad-channel architecture providing four independent comparators in a single integrated circuit
• Low-voltage operation capability with power consumption suitable for battery-powered systems
• Open-drain output configuration allowing flexible interfacing with various logic families
• Extended industrial temperature rating ensuring stable performance in harsh environments

Applications

• Battery-powered monitoring circuits requiring low quiescent current
• General-purpose signal comparison in low-voltage digital systems
• Temperature sensing interfaces utilizing thermistor or sensor outputs
• Window comparator configurations for voltage level detection

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package style and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the SOIC-14 package. Confirm that the required supply voltage range aligns with the 2.7 V to 5.5 V operational limits. Check for any recent product change notices regarding pinout or electrical characteristics updates.

Selection Notes

Select this component when multiple comparators are needed in a space-constrained low-voltage design. Consider the open-drain output requirement for pull-up resistor implementation. Evaluate the 200 ns propagation delay against system speed requirements. Compare input offset voltage specifications if high precision is necessary for the application threshold settings.

Part Context

This part belongs to the LMV3xx series, which serves as the low-voltage counterpart to the industry-standard LM339/LM393 family. It offers reduced current consumption while maintaining similar functional capabilities. The series is designed for applications where power efficiency and single-supply operation are critical constraints.

Replacement Considerations

Direct substitutes include other quad low-voltage comparators from Texas Instruments such as the LMV339IDRG4. Verify pinout compatibility and electrical parameter equivalence before substitution.
