Texas Instruments LMV339IDR

Overview

LMV339IDR from Texas Instruments is a quad low-voltage open-collector comparator operating from 2.7V to 5.5V, delivering 100μA typical supply current, 150mV typical output saturation voltage, and input common-mode range extending to ground - enabling precise threshold detection in battery-powered industrial sensors and power management circuits.

For engineers reviewing the LMV339IDR datasheet, LMV339IDR pinout, LMV339IDR application, or LMV339IDR equivalent, key selection considerations include its SOIC-14 package, rail-to-ground input capability, open-drain output flexibility for level-shifting, and guaranteed operation across –40°C to +125°C ambient temperature.

Technical Context

The LMV339IDR implements a PNP-input stage enabling input common-mode operation down to ground (VICR = –0.1 V to VCC–0.7 V), with differential input offset voltage of ≤7 mV at 25°C and average temperature coefficient of 5 μV/°C. Its open-drain NPN output stage sinks up to 23 mA at 2.7V and 84 mA at 5V, supporting wired-AND logic and interface-level translation.

Propagation delay is 1000 ns (tPHL) and 500 ns (tPLH) at 2.7V with 10 mV overdrive, improving to 200–300 ns at 5V and 100 mV overdrive. Input bias current remains ultra-low (≤250 nA typ), and ESD robustness meets ±2000 V HBM per ANSI/ESDA/JEDEC JS-001.

Key Specifications

Pinout & Package

LMV339IDR is housed in a 14-pin SOIC (D) package measuring 3.91 mm × 8.65 mm, with standard 1.27 mm pitch and RoHS-compliant NiPdAu lead finish. The package supports automated pick-and-place and reflow soldering per MSL Level-1.

FAQ

What is the maximum supply voltage for LMV339IDR?

The absolute maximum supply voltage for LMV339IDR is 5.5 V, with recommended operation between 2.7 V and 5.5 V. Exceeding 5.5 V risks permanent damage per the Absolute Maximum Ratings table. At 5.5 V, the device maintains full functionality including input common-mode range up to VCC–0.7 V and output sinking capability up to 84 mA, as verified in Section 5.7 of the datasheet.

Does LMV339IDR support true ground-referenced input operation?

Yes, LMV339IDR supports input common-mode voltage down to –0.1 V at 25°C, and to 0 V across the full –40°C to +125°C range. This is enabled by its PNP-input architecture, allowing direct connection of sensors referenced to system ground - such as low-side current shunts or thermistors - without external biasing networks.

What is the typical supply current of LMV339IDR at 3.3V?

At 3.3 V supply and 25°C, LMV339IDR draws approximately 100 μA typical supply current, consistent with its 100 μA spec at 2.7 V and 120 μA at 5 V. This ultra-low quiescent current is confirmed in Table 5.5 and Figure 5-1 of the datasheet, making it ideal for always-on battery-powered applications.

Can LMV339IDR outputs be wire-OR'd together?

Yes, all four open-collector outputs of LMV339IDR can be connected to a shared pull-up resistor to implement wired-AND logic or a common fault bus. This configuration is explicitly supported in the Functional Block Diagram (Section 6.2) and Typical Application schematic (Figure 7-1), enabling centralized interrupt generation for multi-threshold monitoring systems.

Is LMV339IDR RoHS compliant and what is its moisture sensitivity level?

Yes, LMV339IDR is RoHS compliant with NiPdAu lead finish and rated MSL Level-1 (unlimited floor life at ≤30°C/60% RH). This information is documented in the PACKAGE OPTION ADDENDUM, confirming suitability for standard surface-mount reflow processes without baking requirements.
