LMV339ID

Overview

The LMV339ID is a quad low-voltage analog comparator manufactured by Texas Instruments, designed for general-purpose applications. It operates within a supply voltage range of 2.7 V to 5.5 V and features an open collector/drain output type. The device exhibits a response time of 200 ns and draws a typical operating supply current of 75 uA. Each channel provides an output current capability of 10 mA. Key electrical parameters include an input offset voltage (Vos) of 7 mV and an input bias current (Ib) of 250 nA. The component supports a common-mode voltage down to -100 mV and functions reliably across a temperature range from -40°C to +125°C.

Feature Summary

• Quad configuration providing four independent comparison channels in a single package
• Low voltage operation optimized for systems powered between 2.7 V and 5.5 V
• Open collector/drain output structure allowing flexible interfacing with various logic families

Applications

• General-purpose signal comparison circuits
• Low-voltage power management monitoring
• Threshold detection in battery-operated devices

Procurement Notes

Verify the specific suffix 'ID' corresponds to the SOIC-14 surface-mount package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the selected supplier provides traceable components matching the Texas Instruments manufacturing specifications to guarantee performance reliability in final assemblies.

Selection Notes

Select this component for designs requiring multiple comparators with minimal power consumption under low supply voltages. The 200 ns propagation delay suits moderate-speed digital interface tasks. Consider the 7 mV input offset voltage for precision requirements; if higher accuracy is needed, evaluate alternative series. The wide industrial temperature range supports deployment in harsh environmental conditions without derating concerns.

Part Context

The LMV339ID belongs to the LMV3xx family, which serves as the low-voltage counterpart to the industry-standard LM339. While the traditional LM339 operates up to 36 V, the LMV339 series is restricted to 2.7–5.5 V supplies but offers significantly lower quiescent current. This family enables space-saving implementations in portable electronics where both voltage constraints and board area are critical design factors.

Replacement Considerations
