Product details
Overview
LMV339MTX/NOPB from Texas Instruments is a quad, low-voltage (2.7 V to 5 V), rail-to-rail input comparator with open-collector outputs, 140–300 µA total supply current at 5 V, 200 ns propagation delay (100 mV overdrive), and −0.1 V to 4.2 V input common-mode range - deployed in battery-powered portable electronics for voltage monitoring and level detection.
For engineers reviewing the LMV339MTX/NOPB datasheet, LMV339MTX/NOPB pinout, LMV339MTX/NOPB application, or LMV339MTX/NOPB equivalent, key selection criteria include supply current per channel, propagation delay under low overdrive, open-collector output compatibility with mixed-voltage logic, and industrial temperature operation (−40°C to +85°C).
Technical Context
The LMV339MTX/NOPB implements four independent comparators using bipolar input and output stages on TI's Submicron BiCMOS process, enabling improved noise immunity versus CMOS-only comparators. Its ground-sensing input stage supports operation with inputs down to −0.1 V, and its open-collector outputs allow wired-OR configurations without external logic.
Each comparator operates with a single 2.7–5 V supply and delivers 200 mV typical saturation voltage at 4 mA sink current. Propagation delay varies with input overdrive: 200 ns (100 mV) and 600 ns (10 mV) at 5 V, supporting both fast threshold detection and precision low-overdrive sensing.

Applications
| Overvoltage Protection Circuit | Battery Charge State Monitor |
|---|---|
|
Use Scenario: Detects when input voltage exceeds safe threshold (e.g., >4.3 V on Li-ion charger line) to disable charging or trigger alert. IC Role / Device Role / Timing Role: Quad comparator configured as window detector - two channels monitor upper/lower bounds; remaining channels provide redundancy or status signaling. Use Value: Prevents cell damage by reacting within microseconds of overvoltage event, leveraging 200 ns propagation delay and rail-to-rail input capability. |
Use Scenario: Monitors battery voltage across multiple states (full, nominal, low, critical) using discrete reference voltages on each comparator input. IC Role / Device Role / Timing Role: Four independent voltage comparators - each assigned to one SOC band; outputs drive LEDs or microcontroller GPIOs. Use Value: Enables precise, low-power state-of-charge indication without ADC overhead - consumes only ~250 µA total at 3.3 V. |
| Portable Device Power Sequencing | Industrial Sensor Threshold Alarm |
|
Use Scenario: Ensures correct power-up order across multiple rails (e.g., 1.2 V core before 3.3 V I/O) in handheld instruments or wearables. IC Role / Device Role / Timing Role: Comparator array compares delayed enable signals against reference thresholds - outputs control MOSFET gate drivers or PMIC sequencing inputs. Use Value: Guarantees robust startup behavior across temperature (−40°C to +85°C) with no external hysteresis required due to built-in input stage stability. |
Use Scenario: Triggers alarm when temperature, pressure, or current sensor output crosses preset safety limits in factory automation equipment. IC Role / Device Role / Timing Role: One comparator per sensor channel - open-collector outputs wired together to single interrupt line on host MCU. Use Value: Reduces BOM count and board area versus discrete solutions; 14-pin TSSOP fits tight industrial module footprints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Wider supply range (2–36 V), higher supply current (500 µA), slower propagation (1.3 µs), no guaranteed 2.7 V operation. | Used in legacy industrial systems with 12/24 V rails; unsuitable for modern 3.3 V battery-powered designs. | Select LM339DR only if operating above 5 V or requiring legacy pinout compatibility - not drop-in for LMV339MTX/NOPB. |
| TLV339IPWR | Lower supply current (38 µA total), rail-to-rail output (push-pull), no open-collector - incompatible with wired-OR or mixed-voltage pull-ups. | Preferred in space-constrained IoT nodes where ultra-low power dominates interface flexibility requirements. | Choose TLV339IPWR when push-pull output suffices and sub-100 µA total current is mandatory - requires schematic redesign. |
Compared with LM339DR and TLV339IPWR, LMV339MTX/NOPB uniquely balances low-voltage operation (2.7 V), open-collector flexibility, and industrial temperature support - making it optimal for new portable and embedded designs requiring wired-OR logic and ground-referenced sensing.

FAQ
What is the maximum recommended supply voltage for LMV339MTX/NOPB?
The absolute maximum supply voltage for LMV339MTX/NOPB is 5.5 V, but the device is specified and characterized for reliable operation between 2.7 V and 5 V. Operating above 5 V risks exceeding absolute maximum ratings and may cause permanent damage or parametric shift. For long-term reliability in production, maintain V+ ≤ 5 V per the recommended operating conditions table in the SNOS018H datasheet.
Does LMV339MTX/NOPB support rail-to-rail input operation?
LMV339MTX/NOPB supports rail-to-rail input common-mode range down to −0.1 V below V− and up to 4.2 V at 5 V supply - meaning it fully covers ground (V−) and approaches V+ closely, but does not extend to the positive rail. This "ground-sensing" capability enables direct interfacing with sensors and signals referenced to system ground without level-shifting circuitry.
Can LMV339MTX/NOPB outputs be connected together for wired-OR logic?
Yes - all four outputs of LMV339MTX/NOPB are open-collector and electrically isolated, allowing them to be tied together with a single pull-up resistor to implement wired-OR logic. This configuration is commonly used for fault-bus architectures, where any comparator asserting LOW pulls the shared line LOW, signaling an alarm condition to a microcontroller interrupt pin.
What is the typical propagation delay of LMV339MTX/NOPB at 3.3 V supply?
While the datasheet specifies propagation delay at 2.7 V and 5 V, interpolation shows LMV339MTX/NOPB delivers ~250 ns (100 mV overdrive) at 3.3 V - consistent with its BiCMOS architecture and confirmed by typical characteristic curves. This makes it suitable for real-time threshold detection in portable audio, power management, and sensor interface applications running from standard 3.3 V LDOs.
Is LMV339MTX/NOPB RoHS compliant and lead-free?
Yes - LMV339MTX/NOPB carries the "/NOPB" suffix, indicating it is lead-free and RoHS compliant per EU Directive 2011/65/EU. The "MTX" tape-and-reel packaging variant meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), suitable for standard SMT assembly without baking.
