Product details

Overview

LMV339M/NOPB 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 140–200 µA total supply current (35–50 µA/channel), 200 mV typical output saturation voltage at 4 mA sink, and 200 ns propagation delay (5-V supply, 100-mV overdrive). It is used in battery-powered voltage monitoring, window detection, and level-shifting circuits.

For engineers reviewing the LMV339M/NOPB datasheet, LMV339M/NOPB pinout, LMV339M/NOPB application, or LMV339M/NOPB equivalent, key selection considerations include its rail-to-rail input common-mode range (−0.1 V to 4.2 V at 5 V), industrial temperature rating (−40°C to +85°C), SOIC-14 package footprint, and compatibility with wired-OR logic configurations.

Technical Context

The LMV339M/NOPB implements four independent voltage comparators with bipolar input stages and NPN open-collector output transistors. Its input stage supports ground-sensing operation down to −0.1 V, enabling direct interface with signals referenced to system ground. Each channel operates with no internal hysteresis and requires external pull-up resistors (1 kΩ to 10 kΩ) on outputs.

It uses TI's Submicron Silicon-Gate BiCMOS process to achieve low power without sacrificing noise immunity. The device is functionally compatible with the legacy LM339 but draws less than half the supply current at 5 V and supports operation down to 2.7 V - making it suitable for modern low-power embedded systems where supply headroom is limited.

Key Specifications

Parameter	Value and Actual Design Meaning

Input Offset Voltage	1.7–7 mV (typ) - ensures reliable threshold detection within ±10 mV accuracy for general-purpose sensing applications.
Propagation Delay	200 ns (typ, 100-mV overdrive, 5 V) - supports response to fast-changing analog signals such as pulse edges or clock-derived references.
Output Saturation Voltage	200 mV at 4 mA sink - guarantees clean logic-low levels when driving TTL or CMOS inputs with standard pull-up resistors.
Input Common-Mode Range	−0.1 V to 4.2 V at 5 V - permits direct comparison of ground-referenced sensors or signals near supply rails.

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	Higher supply current (500 µA typical), wider supply range (2 V to 36 V), slower propagation (1.3 µs), no guaranteed 2.7-V operation.	Used in legacy industrial controls and high-voltage analog systems; not optimized for battery-powered devices.	Select LM339DR only if wide supply tolerance or high-voltage robustness is required - not for low-power portable designs.
TLV339IPW	Lower supply current (12 µA/channel), rail-to-rail input, push-pull output (no pull-up needed), smaller TSSOP-14 package.	Suitable for ultra-low-power IoT nodes and wearables; incompatible with wired-OR due to active-high output stage.	Choose TLV339IPW when minimizing current draw is critical and logic interface does not require open-collector flexibility.

Compared with LMV339M/NOPB, LM339DR consumes ~3× more current and lacks guaranteed 2.7-V operation, while TLV339IPW offers superior efficiency but sacrifices wired-OR capability and voltage-level translation versatility.

FAQ

What is the maximum recommended pull-up resistor value for LMV339M/NOPB outputs?

The LMV339M/NOPB datasheet specifies that output pull-up resistors should range between 1 kΩ and 10 kΩ. A 10 kΩ resistor limits sink current to ~500 µA at 5 V while maintaining adequate rise time for most digital interfaces. Higher values increase rise time and susceptibility to noise; lower values increase power consumption unnecessarily. For 3.3 V systems, 4.7 kΩ is commonly used to balance speed and efficiency.

Does LMV339M/NOPB support true rail-to-rail input operation?

No - LMV339M/NOPB supports input common-mode voltage down to −0.1 V (below ground) and up to 0.8 V below V+, giving it ground-sensing capability but not full rail-to-rail input range. At 5 V supply, the usable input range is −0.1 V to 4.2 V. This differs from rail-to-rail-input comparators like TLV339, which accept signals from V− to V+.

Can LMV339M/NOPB drive a standard TTL input directly?

Yes - LMV339M/NOPB can drive TTL inputs when its open-collector output is pulled up to 5 V. With a 10 kΩ pull-up and 4 mA sink capability, it achieves <0.4 V saturation voltage, satisfying TTL logic-low requirements. However, ensure the pull-up voltage does not exceed the LMV339M/NOPB's V+ supply - e.g., do not pull up to 5 V if V+ = 3.3 V.

Is LMV339M/NOPB pin-compatible with LM339?

Yes - LMV339M/NOPB uses the same SOIC-14 pinout as LM339, including identical assignments for all inputs, outputs, and power pins. This allows drop-in replacement in existing LM339 designs to reduce supply current and extend battery life, provided the 2.7–5 V supply range meets system requirements.

What is the typical input bias current of LMV339M/NOPB at 25°C and 5 V supply?

The typical input bias current of LMV339M/NOPB is 25 nA at 25°C and 5 V supply, with a maximum of 400 nA across the full −40°C to +85°C temperature range. This low bias current minimizes loading errors in high-impedance reference or sensor circuits, such as those using megaohm-scale divider networks or ceramic capacitors.
