LMV339M/NOPB

Overview

The LMV339M/NOPB is a quad analog comparator manufactured by Texas Instruments, designed for low-voltage single-supply operation. It features four independent differential comparators in a 14-pin SOIC-14 surface-mount package. The device operates within a supply voltage range of 2.7 V to 5 V and supports an operating temperature range from -40°C to +85°C. Key electrical specifications include a typical response time of 450 ns, a maximum input offset voltage of 7 mV, and an input bias current of 250 nA. Each channel provides an open collector or open drain output type with a maximum output current capability of 6 mA.

Feature Summary

• Quad configuration providing four independent differential comparators in a single integrated circuit
• Optimized for low-voltage single-supply applications with operation down to 2.7 V
• Rail-to-rail compatible input common-mode range that includes ground potential
• Open collector/open drain output structure allowing flexible logic interface compatibility

Applications

• Low-voltage battery-powered monitoring systems
• Portable consumer electronics requiring space-saving SMD packaging
• General-purpose signal conditioning circuits
• Temperature sensing interfaces using thermistors or RTDs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and RoHS status. Ensure the selected package variant matches the required PCB footprint dimensions. Confirm the operational temperature grade aligns with the intended environmental conditions before finalizing procurement orders.

Selection Notes

Select this component when system design requires multiple comparators within a constrained voltage envelope below 5 V. The open-drain output necessitates external pull-up resistors; verify resistor values match the target logic levels. Consider the 450 ns propagation delay for high-speed switching requirements compared to faster alternatives.

Part Context

This part belongs to the LMV3xx series, which serves as the low-voltage counterpart to the industry-standard LM339 family. While the legacy LM339 supports higher voltages up to 36 V, the LMV339M/NOPB is engineered specifically for modern portable devices where power efficiency and reduced supply voltage are critical design constraints.

Replacement Considerations
