Product details
Overview
LMV339MX/NOPB from Texas Instruments is a quad, low-voltage, rail-to-rail input comparator with open-collector outputs, designed for space-constrained portable systems operating from 2.7 V to 5 V. It delivers 60 µA/channel supply current, 200 ns propagation delay (at 5 V), and input common-mode range extending to ground - enabling direct sensing of signals near 0 V in battery-powered applications such as power monitoring and voltage threshold detection.
For engineers reviewing the LMV339MX/NOPB datasheet, LMV339MX/NOPB pinout, LMV339MX/NOPB application, or LMV339MX/NOPB equivalent, key selection criteria include its guaranteed 2.7-V/5-V operation, industrial −40°C to +85°C temperature range, 200 mV output saturation voltage at 4 mA sink, and compatibility with wired-OR logic configurations using external pull-up resistors.
Technical Context
The LMV339MX/NOPB implements four independent comparators with bipolar input stages and NPN open-collector output transistors, optimized for noise immunity and low-power operation. Its input stage supports common-mode voltages from −0.1 V to 4.2 V (at 5 V supply), and its output requires an external pull-up resistor (1 kΩ to 10 kΩ) to function in wired-OR or level-shifting configurations.
It operates across a single 2.7–5 V supply, with no dual-supply requirement, and features internal ESD protection rated at ±800 V HBM. The device uses TI's Submicron Silicon-Gate BiCMOS process, ensuring performance parity with legacy LM339 while reducing supply current by >80%.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - enables direct integration into 3.3 V and 5 V battery-powered systems without level-shifting. |
| Supply Current per Channel | 60 µA typical at 5 V - allows ultra-low quiescent power in always-on monitoring circuits (e.g., battery voltage supervisors). |
| Propagation Delay | 200 ns typical (high-to-low, 100 mV overdrive, 5 V) - supports fast response in overvoltage/undervoltage lockout and signal edge detection. |
| Input Offset Voltage | 7 mV typical - sufficient for coarse thresholding (e.g., battery charge-state indication), not precision analog comparison. |
| Output Saturation Voltage | 200 mV at 4 mA sink - ensures reliable logic-low assertion when driving TTL or CMOS inputs with standard pull-ups. |
| Input Common-Mode Range | −0.1 V to 4.2 V (5 V supply) - permits ground-referenced input sensing without external biasing networks. |
| ESD Rating (HBM) | ±800 V - meets basic handling robustness requirements for consumer electronics assembly environments. |
Pinout & Package
LMV339MX/NOPB is packaged in a 14-pin SOIC (Small Outline Integrated Circuit) with body size 8.65 mm × 3.91 mm, lead pitch 1.27 mm, and surface-mount footprint compatible with standard reflow processes.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Open-collector output for comparator A - requires external pull-up; sinks current when active low. |
| 2 | IN− A | Inverting input for comparator A - accepts reference or feedback voltage for threshold comparison. |

| 9 | IN+ D | Non-inverting input for comparator D - completes full quad-channel sensing capability. |
| 10 | IN− D | Inverting input for comparator D - supports fourth independent voltage window or fault condition. |
| 11 | OUT D | Open-collector output for comparator D - electrically isolated from other outputs for flexible routing. |
| 12 | V+ | Positive supply terminal - accepts 2.7–5 V DC; powers all four comparators and output stages. |
| 13 | OUT C | Open-collector output for comparator C - shares no internal connection with other outputs. |
| 14 | OUT B | Open-collector output for comparator B - supports independent logic-level translation per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent comparators | Enables simultaneous monitoring of four distinct voltage thresholds (e.g., battery low/high, thermal warning/critical, supply OK/fail, sensor fault/normal) on one IC. |
| Open-collector outputs | Allows wired-OR logic implementation (e.g., single fault bus), level shifting across voltage domains, and direct interface to TTL/CMOS loads with appropriate pull-up. |
| Rail-to-rail input common-mode range including ground | Eliminates need for input biasing resistors when sensing signals referenced to system ground - reduces BOM count and PCB area. |
| Low 60 µA/channel supply current | Extends battery life in portable devices; supports continuous monitoring in energy-sensitive applications like wearables and IoT sensors. |
| Guaranteed operation at 2.7 V and 5 V | Ensures functional reliability across full Li-ion battery discharge curve (4.2 V → 2.7 V) without recalibration or supply regulation. |
Applications
| Battery Voltage Monitoring | Power Supply Sequencing |
|---|---|
|
Use Scenario: Monitoring Li-ion battery voltage during charge/discharge cycles to trigger low-battery alerts and overvoltage cutoffs. IC Role / Device Role / Timing Role: Quad comparator compares divided battery voltage against four fixed thresholds (e.g., 4.2 V, 3.8 V, 3.3 V, 2.8 V) to generate discrete status flags. Use Value: Enables precise state-of-charge estimation and safe shutdown before deep discharge, leveraging ground-sensing inputs and low quiescent current. |
Use Scenario: Ensuring correct power-up order across multiple rails (e.g., 3.3 V, 1.8 V, 1.2 V) in FPGA or microprocessor systems. IC Role / Device Role / Timing Role: Each comparator monitors one rail's voltage and asserts a ready signal only after crossing its threshold; outputs feed enable pins or reset controllers. Use Value: Prevents latch-up or configuration errors by enforcing strict sequencing - open-collector outputs simplify OR-ing of multiple "power good" signals. |
| Window Comparator for Sensor Signals | Over-Temperature Detection |
|
Use Scenario: Validating analog sensor outputs (e.g., thermistor, pressure transducer) remain within acceptable operational bounds. IC Role / Device Role / Timing Role: Two comparators form upper/lower limits (window); third and fourth detect out-of-range conditions for alarm latching or ADC gating. Use Value: Provides real-time signal integrity validation without MCU intervention - rail-to-rail inputs accept unbuffered sensor outputs directly. |
Use Scenario: Detecting thermal runaway in motor drivers, power converters, or LED arrays using NTC thermistor feedback. IC Role / Device Role / Timing Role: One comparator triggers fan control at moderate temperature; second initiates hard shutdown at critical threshold; remaining channels monitor auxiliary zones. Use Value: Delivers fail-safe thermal management with minimal external components - 200 ns response ensures rapid reaction to sudden temperature spikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher 1.6 mA/channel supply current; wider 2–36 V supply range; slower 1.3 µs propagation delay; no guaranteed 2.7 V operation. | Preferred in industrial systems with wide-input supplies and less stringent power budgets; unsuitable for sub-3 V battery operation. | Select LM339DR only if operating above 3 V and requiring legacy compatibility or higher drive strength. |
| TLV339IPW | Lower 15 µA/channel supply current; rail-to-rail output (push-pull); smaller TSSOP-14 package; 175 ns propagation delay; same 2.7–5 V range. | Better suited for ultra-low-power designs needing active-high outputs or tighter board space; lacks open-collector flexibility for wired-OR. | Choose TLV339IPW when minimizing current draw is critical and push-pull outputs suffice - avoid if wired-OR or level-shifting is required. |
Compared with LMV339MX/NOPB, LM339DR consumes ~26× more current and cannot operate below 3 V, making it incompatible with modern low-voltage portable designs; TLV339IPW offers superior efficiency but sacrifices open-collector functionality essential for shared fault buses and mixed-voltage interfacing.

FAQ
What is the maximum operating supply voltage for LMV339MX/NOPB?
The absolute maximum supply voltage for LMV339MX/NOPB is 5.5 V, but the recommended operating range is 2.7 V to 5 V. Operation above 5 V risks permanent damage, and performance parameters (e.g., propagation delay, offset voltage) are only specified and guaranteed within the 2.7–5 V range per the official datasheet SNOS018H.
Does LMV339MX/NOPB support rail-to-rail input operation?
Yes, LMV339MX/NOPB supports rail-to-rail input common-mode voltage range, extending from −0.1 V below ground to 4.2 V with a 5 V supply. This allows direct connection of ground-referenced signals (e.g., battery sense lines) without external biasing, a key feature confirmed in Section 6.7 of the LMV339-N datasheet.
Can LMV339MX/NOPB outputs be connected together for wired-OR logic?
Yes, LMV339MX/NOPB features open-collector outputs that are explicitly designed for wired-OR configurations. As stated in Section 7.3.1 of the datasheet, multiple outputs can share a single pull-up resistor to implement functions like fault-bus aggregation or window comparator logic without additional discrete components.
What is the typical propagation delay of LMV339MX/NOPB at 3.3 V supply?
While the datasheet specifies propagation delay at 2.7 V and 5 V (200 ns typical at 5 V, 1000 ns at 2.7 V with 10 mV overdrive), no official value is published for 3.3 V. Engineers should interpolate between these points or validate timing in-system, as LMV339MX/NOPB performance at 3.3 V falls within its guaranteed 2.7–5 V operating range but lacks a dedicated test condition.
Is LMV339MX/NOPB pin-compatible with LM339?
No, LMV339MX/NOPB is not pin-compatible with standard LM339 variants. Although both are quad comparators in 14-pin packages, LMV339MX/NOPB uses SOIC-14 with pin assignments matching TI's LMV339 family (e.g., V− on pin 8, V+ on pin 12), whereas LM339DR places V+ on pin 16 and V− on pin 4 in its SOIC-14 variant - requiring PCB layout changes for substitution.
