Product details
Overview
LMV339IPW from Texas Instruments is a quad general-purpose low-voltage comparator IC with open-collector outputs, operating from 2.7V to 5.5V supply, consuming 100μA typical supply current at 2.7V, featuring input common-mode range extending to ground and 150mV typical output saturation voltage - used in server PSU monitoring, vacuum robot motion control, and building automation sensor interfaces.
For engineers reviewing the LMV339IPW datasheet, LMV339IPW pinout, LMV339IPW application, or LMV339IPW equivalent, key selection criteria include its TSSOP-14 package footprint, quad-channel open-drain architecture, rail-to-ground input capability, and compatibility with 3.3V/5V logic level shifting in space-constrained industrial systems.
Technical Context
The LMV339IPW implements four independent PNP-input comparators with open-drain NPN output stages, enabling flexible pull-up configuration and wired-AND logic functionality. Its input stage supports common-mode voltages from –0.1V to VCC–0.7V, allowing direct interfacing with ground-referenced sensors and low-voltage microcontrollers.
Each comparator exhibits 7mV typical input offset voltage (25°C), 5μV/°C average temperature coefficient, and propagation delays of 600ns (tPHL) / 450ns (tPLH) at 5V supply with 100mV overdrive - optimized for fast response in power sequencing and fault detection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables simultaneous monitoring of four independent voltage thresholds in single-package space. |
| Supply Voltage Range | 2.7V to 5.5V - supports direct operation from 3.3V and 5V rails without regulation. |
| Supply Current (Typ) | 100μA at 2.7V - enables battery-powered or ultra-low-power applications like cordless tool status sensing. |
| Input Common-Mode Range | –0.1V to VCC–0.7V - allows ground-referenced inputs and compatibility with 0–3.3V sensor outputs. |
| Output Type | Open-collector - permits level translation, wired-AND logic, and interface with higher-voltage logic families. |
| Propagation Delay (5V) | 600ns high-to-low, 450ns low-to-high - suitable for sub-microsecond timing-critical functions such as overvoltage latch. |
| Input Offset Voltage (Typ) | 7mV at 25°C - ensures reliable threshold detection with ≤10mV hysteresis design margin. |
Pinout & Package
TSSOP-14 package (4.40mm × 5.00mm body size), lead-free with NiPdAu finish, moisture sensitivity level 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 13 | Comparator output (OUT1–OUT4) | Open-collector NPN drain - requires external pull-up; sinks up to 23mA at 2.7V for driving LEDs or logic inputs. |
| 3, 5, 7, 9 | Negative input (IN1– to IN4–) | Inverting input terminal per comparator - accepts signals down to –0.1V for ground-referenced differential sensing. |
| 4, 6, 8, 10 | Positive input (IN1+ to IN4+) | Non-inverting input terminal per comparator - supports common-mode range up to VCC–0.7V. |
| 11 | GND | Analog ground reference - must be connected to system ground plane for stable offset and noise immunity. |
| 12 | VCC+ | Positive supply pin - decoupling capacitor (0.1μF) required between Pin 12 and Pin 11 for transient rejection. |
Key Features
| Feature | Design Value |
|---|---|
| Low supply current | 100μA typical (all four channels @ 2.7V) - reduces quiescent power in always-on monitoring circuits. |
| Rail-to-ground input | Common-mode range includes 0V - eliminates need for level-shifting circuitry when interfacing with ground-referenced sensors. |
| Open-collector output | Supports mixed-voltage system interfacing - e.g., 3.3V comparator driving 5V logic via 5.1kΩ pull-up. |
| Wide temperature range | –40°C to +125°C operation - qualified for industrial and automotive under-hood environments. |
| ESD robustness | ±2000V HBM - withstands handling and board-level ESD events without functional degradation. |

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 |
|---|---|---|---|
| LMV339IPWR | Same die, TSSOP-14, active production status; identical electrical specs and pinout. | No functional difference - designed as direct replacement for LMV339IPW in new designs. | Select LMV339IPWR for volume procurement and guaranteed long-term availability. |
| TLV339IPW | Lower supply current (55μA typ @ 2.7V), wider supply range (1.6V–5.5V), but reduced output sink current (8mA vs 23mA). | Better suited for ultra-low-power battery applications; less suitable for driving heavier loads like LEDs or optocouplers. | Choose TLV339IPW only when <60μA total supply budget is critical and load drive <10mA. |
Compared with LMV339IPW, LMV339IPWR offers assured supply continuity and identical performance, while TLV339IPW trades output drive strength for lower quiescent current - making LMV339IPWR the preferred drop-in alternative for legacy LMV339IPW designs.

FAQ
What is the operating temperature range for the LMV339IPW?
The LMV339IPW is specified to operate across –40°C to +125°C ambient temperature. This wide range is validated per TI's production testing and supports deployment in industrial environments such as factory automation controllers and automotive under-hood modules where thermal stress is significant. The LMV339IPW maintains its 7mV typical input offset and 100μA supply current specifications across this full range.
Does the LMV339IPW support rail-to-rail input operation?
The LMV339IPW does not support full rail-to-rail input - its input common-mode range extends from –0.1V to VCC–0.7V. This means it accepts signals down to ground (enabling true ground-referenced sensing) but cannot reliably process inputs within ~700mV of VCC. For example, at 5V supply, maximum valid input is ~4.3V. This limitation stems from its PNP input stage architecture, documented in Section 6.3 of the LMV339 datasheet.
Can the LMV339IPW outputs drive an LED directly?
Yes, the LMV339IPW outputs can drive an LED directly when configured with an appropriate series resistor and external pull-up. Each open-collector output sinks up to 23mA (typical at 2.7V, VO ≤ 1.5V), sufficient for standard indicator LEDs. For a 20mA red LED with 1.8V forward voltage powered from 5V, a 150Ω pull-up resistor yields ~21mA sink current - well within LMV339IPW's safe operating area per Section 5.5 of the datasheet.
Is the LMV339IPW pin-compatible with the LM339?
No, the LMV339IPW is not pin-compatible with the legacy LM339. While both are quad comparators in 14-pin packages, the LM339 uses SOIC-D14 (3.91mm × 8.65mm) whereas the LMV339IPW uses TSSOP-PW14 (4.40mm × 5.00mm) - differing in body size, pin pitch (0.65mm vs 1.27mm), and thermal pad presence. Electrical compatibility exists (same pin functions), but PCB layout redesign is required due to mechanical incompatibility.
What is the recommended bypass capacitor for the LMV339IPW supply pin?
Texas Instruments recommends a 0.1μF ceramic capacitor placed between Pin 12 (VCC+) and Pin 11 (GND), located as close as possible to the device. This value is specified in Section 9.2 (Layout Example) and Section 8 (Power Supply Recommendations) to suppress supply transients that could shift the input common-mode range and cause erroneous comparisons - especially critical in noisy environments like motor-driven systems.
