Product details
Overview
LMV339MT/NOPB from Texas Instruments is a quad low-voltage comparator with open-collector outputs, designed for space-constrained portable systems operating from 2.7 V to 5 V. It delivers 140–200 µA total supply current (all four channels), 200 ns propagation delay at 5 V, and input common-mode range extending to ground - enabling direct sensing of near-ground signals in battery-powered applications like power rail monitoring and sensor threshold detection.
For engineers reviewing the LMV339MT/NOPB datasheet, LMV339MT/NOPB pinout, LMV339MT/NOPB application, or LMV339MT/NOPB equivalent, key selection criteria include its guaranteed 2.7-V operation, industrial temperature range (−40°C to +85°C), low output saturation voltage (200 mV at 4 mA), and compatibility with wired-OR logic configurations via open-collector outputs.
Technical Context
The LMV339MT/NOPB implements four independent voltage comparators using bipolar input and output stages fabricated on TI's Submicron BiCMOS process - delivering improved noise immunity over CMOS-only alternatives while maintaining ultra-low quiescent current. Its input stage supports rail-to-rail common-mode operation down to −0.1 V (below ground) and up to 4.2 V (at 5-V supply), and its open-collector outputs require external pull-up resistors (1 kΩ to 10 kΩ) for proper logic-level translation.
Each comparator operates as a high-gain differential amplifier with hysteresis-free switching behavior unless externally configured. The device supports single-supply operation only (no dual ±VCC), and its output sink capability reaches 10 mA at 5 V (VO ≤ 1.5 V), enabling direct interface with TTL and CMOS loads without level-shifting circuitry.

Applications
| Battery Voltage Monitor | Power-Rail Sequencing |
|---|---|
|
Use Scenario: Monitoring individual Li-ion cell voltages during charging/discharging to prevent overvoltage or deep discharge. IC Role / Device Role / Timing Role: Quad comparator compares each cell voltage against fixed thresholds (e.g., 4.25 V, 3.0 V) using resistor-divider references. Use Value: Enables precise per-cell protection with one IC instead of four discrete comparators - saving PCB area and BOM cost. |
Use Scenario: Ensuring correct power-up order across multiple supply rails (e.g., 1.2 V core before 3.3 V I/O) in FPGA or SoC systems. IC Role / Device Role / Timing Role: Each comparator monitors a rail and asserts a "ready" flag only after its target voltage is reached and stable. Use Value: Prevents latch-up or configuration failure by generating clean, sequenced enable signals without microcontroller intervention. |
| Window Comparator | Zero-Crossing Detector |
|
Use Scenario: Validating that an analog sensor output (e.g., temperature, pressure) remains within safe operational bounds. IC Role / Device Role / Timing Role: Two comparators form upper/lower thresholds; third channel ORs outputs to generate fault flag when outside window. Use Value: Detects out-of-range conditions with <200 ns latency and no software overhead - critical for safety-critical subsystems. |
Use Scenario: Converting AC line voltage or motor back-EMF into clean digital timing edges for phase control or RPM measurement. IC Role / Device Role / Timing Role: Single comparator detects crossing of 0 V (using V− = GND and reference = 0 V), with hysteresis added externally. Use Value: Provides jitter-free zero-crossing pulses even with noisy inputs - essential for TRIAC dimming and BLDC commutation timing. |
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 to 36 V), higher supply current (500 µA typ), slower propagation (1.3 µs), no guaranteed 2.7-V operation | Suitable for industrial 12/24-V systems but not optimized for sub-3-V battery operation | Select LM339DR only if wide supply range and high-voltage tolerance outweigh need for low power and fast response. |
| TLV339IPWR | Lower supply current (80 µA typ), rail-to-rail input, push-pull output (no pull-up required), same 2.7–5-V range | Eliminates external pull-up resistors but lacks wired-OR capability; less suitable for window detection | Choose TLV339IPWR when board space is constrained and push-pull logic simplifies design - avoid if wired-OR or level translation is needed. |
Compared with LMV339MT/NOPB, LM339DR trades speed and low-voltage efficiency for ruggedness at higher supplies, while TLV339IPWR reduces component count with push-pull outputs but sacrifices flexible logic interfacing - making LMV339MT/NOPB optimal for battery-powered systems requiring both low power and wired-OR configurability.

FAQ
What is the maximum output sink current specification for LMV339MT/NOPB?
The LMV339MT/NOPB specifies a minimum output sink current of 8 mA and a typical value of 10 mA at 5 V supply when VO ≤ 1.5 V. This rating applies per channel and is validated across the full industrial temperature range (−40°C to +85°C). The LMV339MT/NOPB can reliably drive standard TTL inputs, small LEDs, or MOSFET gates without external buffering - provided the external pull-up resistor is sized appropriately (1–10 kΩ) to maintain voltage margins.
Does LMV339MT/NOPB support dual-supply operation?
No, LMV339MT/NOPB is specified for single-supply operation only, with V− connected to ground (0 V) and V+ supplied from 2.7 V to 5 V. Its input common-mode range extends to −0.1 V below ground, allowing it to accept slightly negative inputs in single-supply configurations - but it does not support true split-rail operation (e.g., ±2.5 V). Attempting dual-supply biasing may violate absolute maximum ratings and cause malfunction.
Can LMV339MT/NOPB replace LM339 in existing designs?
LMV339MT/NOPB can replace LM339 in many low-voltage applications due to identical pinout in SOIC-14 and functional equivalence, but only if the supply voltage is ≥2.7 V and speed requirements exceed 1.3 µs. At 5 V, LMV339MT/NOPB offers 200 ns propagation vs. LM339's 1.3 µs, and draws ~60% less current. However, LM339 supports up to 36 V and handles larger input differentials - so verify supply range, input voltage limits, and timing margins before substitution.
What is the recommended pull-up resistor value for LMV339MT/NOPB outputs?
Texas Instruments recommends a pull-up resistor between 1 kΩ and 10 kΩ for LMV339MT/NOPB outputs. A 4.7 kΩ resistor is commonly used to balance rise time (<100 ns with 10 pF load), power dissipation (<1 mW at 5 V), and noise immunity. Lower values improve speed but increase supply current; higher values reduce power but slow transitions and increase susceptibility to noise - especially in high-impedance routing or noisy environments.
Is LMV339MT/NOPB RoHS compliant and lead-free?
Yes, LMV339MT/NOPB is RoHS compliant and lead-free. The "/NOPB" suffix explicitly denotes "No Lead (Pb)-Free" packaging per TI's part numbering convention. It meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) and is compatible with standard Pb-free reflow profiles. Full compliance documentation, including substance declarations and test reports, is available through TI's Quality & Environmental Information portal.
