Product details
Overview
LMV339M from Texas Instruments is a quad low-voltage comparator IC with open-collector outputs, designed for space-constrained portable electronics operating from 2.7 V to 5 V. It delivers 60 µA/channel supply current, 200 mV output saturation voltage at 4 mA sink, and 200 ns propagation delay (5-V, 100-mV overdrive), enabling battery-powered voltage monitoring and threshold detection in handheld devices.
For engineers reviewing the LMV339M datasheet, LMV339M pinout, LMV339M application, or LMV339M equivalent, key selection considerations include its 14-pin SOIC/TSSOP package, ground-sensing input range (−0.1 V to 4.2 V at 5 V), industrial temperature rating (−40°C to 85°C), and compatibility with wired-OR logic and CMOS/TTL interfacing.
Technical Context
The LMV339M implements four independent comparators using bipolar input and output stages on TI's Submicron BiCMOS process, delivering improved noise immunity versus CMOS-only alternatives. Its open-collector outputs require external pull-up resistors (1 kΩ–10 kΩ) and support wired-OR configurations for window detection or alarm aggregation.
It operates across 2.7 V–5 V single-supply rails with input common-mode range extending 0.1 V below ground and up to 0.8 V below V+, enabling direct sensing of signals referenced to system ground. Propagation delay varies with overdrive (200 ns typical at 100 mV, 600 ns at 10 mV under 5-V conditions).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports direct integration into Li-ion (3.3 V/3.7 V) and USB-powered systems without LDO regulation. |
| Supply Current per Channel | 60 µA typical at 5 V - enables >1-year operation on coin-cell batteries when used intermittently in wake-up circuits. |
| Input Offset Voltage | 1.7 mV (min), 7 mV (typ) - ensures reliable detection of small analog signal deviations (e.g., battery voltage sag, sensor thresholds). |
| Propagation Delay | 200 ns (typ, 5 V, 100-mV overdrive) - suitable for medium-speed digital event triggering (e.g., power-fail detection, motor commutation timing). |
| Output Saturation Voltage | 200 mV at 4 mA sink - guarantees clean logic-low levels when driving 3.3-V or 5-V CMOS inputs with margin. |
| Input Common-Mode Range | −0.1 V to 4.2 V (5 V supply) - allows direct connection to ground-referenced sensors and rail-to-rail input monitoring. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automotive cabin applications without derating. |

Use Scenario: Monitoring Li-ion cell voltage during charge/discharge cycles to trigger low-battery warnings and prevent deep discharge. IC Role / Device Role / Timing Role: Quad comparator compares cell voltage against four precision thresholds (e.g., 4.2 V, 3.8 V, 3.5 V, 3.0 V) using resistor-divider references. Use Value: Enables granular state-of-charge indication and safe cutoff at 3.0 V while maintaining <60 µA total supply draw. |
Use Scenario: Detecting excessive current in DC motor drive circuits via shunt resistor voltage drop to initiate shutdown before thermal damage. IC Role / Device Role / Timing Role: One comparator channel compares amplified shunt voltage against adjustable overcurrent threshold; output drives gate driver disable line. Use Value: 200 ns response time ensures motor current is cut within microseconds of fault onset, protecting MOSFETs and windings. |
| USB Power Negotiation Interface | Multi-Zone Temperature Alarm |
|
Use Scenario: Validating VBUS presence and detecting USB suspend/resume states in portable peripherals using voltage-level translation. IC Role / Device Role / Timing Role: Comparator A senses VBUS ≥4.4 V (valid USB power); comparator B checks for <0.8 V (suspend mode) on data lines. Use Value: Open-collector outputs interface directly to 3.3-V microcontroller GPIOs with no level-shifter, reducing BOM count. |
Use Scenario: Supervising temperature across four PCB zones (CPU, memory, power stage, enclosure) using NTC thermistors. IC Role / Device Role / Timing Role: Each comparator monitors one thermistor divider output against fixed reference; outputs feed OR-gated interrupt line. Use Value: Single 14-pin SOIC replaces four discrete comparators, saving 28 mm² board area and simplifying layout routing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Wider supply range (2 V–36 V), higher 1.6 mA/channel supply current, slower 1.3 µs propagation delay, same SOIC-14 pinout. | Preferred for high-voltage industrial systems; unsuitable for sub-3-V battery operation or ultra-low-power designs. | Select LM339DR only when operating above 5 V or requiring legacy compatibility; LMV339M is superior for 2.7–5 V portable use. |
| TLV339IPWR | Lower 35 µA/channel supply current, rail-to-rail input, 1.5 µs propagation delay, 5-V max supply, TSSOP-14 package only. | Better for nano-power wake-up circuits but lacks 5-V robustness and SOIC option; not drop-in compatible due to different input structure. | Choose TLV339IPWR for longest battery life where speed <500 ns is acceptable; LMV339M offers better speed/power trade-off at 5 V. |
Compared with LM339DR and TLV339IPWR, the LMV339M uniquely balances 200 ns speed, 60 µA/channel efficiency, and 2.7–5 V flexibility in both SOIC and TSSOP packages-making it optimal for next-generation portable and embedded systems requiring responsive, low-power analog decision-making.

FAQ
What is the maximum supply voltage for LMV339M?
The absolute maximum supply voltage for LMV339M is 5.5 V, but the recommended operating range is 2.7 V to 5 V. Operation above 5 V risks permanent damage and invalidates parametric guarantees. At 5 V, LMV339M achieves its specified 200 ns propagation delay and 200 mV output saturation voltage-key metrics verified in TI's SNOS018H datasheet.
Does LMV339M support rail-to-rail input operation?
No, LMV339M does not support rail-to-rail input. Its input common-mode voltage range extends from −0.1 V to 4.2 V at 5 V supply-covering ground but stopping 0.8 V below V+. This ground-sensing capability enables direct interface with shunt-based current monitors and other ground-referenced signals, but excludes full rail-to-rail analog input coverage.
Can LMV339M outputs be wired together?
Yes, LMV339M's open-collector outputs can be safely wired together with a single pull-up resistor to implement wired-OR logic. This is explicitly supported in TI's datasheet and commonly used for window comparators or aggregated fault signaling. The LMV339M output transistor can sink up to 10 mA per channel, and the shared pull-up should be sized between 1 kΩ and 10 kΩ for reliable switching.
What is the input offset voltage specification for LMV339M?
The LMV339M has a guaranteed maximum input offset voltage of 9 mV across temperature (−40°C to +85°C) and 7 mV typical at 25°C. This parameter is critical for accurate threshold detection-e.g., in battery voltage monitoring where ±5 mV error could misfire low-battery alerts. The offset drift is 5 µV/°C, ensuring stability across operating environments.
Is LMV339M available in both SOIC and TSSOP packages?
Yes, LMV339M is offered in two industry-standard 14-pin packages: SOIC (8.65 mm × 3.91 mm) and TSSOP (5.00 mm × 4.40 mm). Both share identical pinout, electrical specifications, and thermal performance (θJA = 145°C/W for SOIC, 155°C/W for TSSOP). Designers may select based on board density requirements without redesigning schematics or layouts.
