Product details
Overview
LMV339IPT from STMicroelectronics is a quad low-voltage rail-to-rail input comparator with open-drain outputs, designed for space-constrained portable systems. It operates from 2.7 V to 5.0 V, consumes only 25–150 µA supply current across temperature, delivers 200–425 ns propagation delay (overdrive-dependent), and supports full industrial temperature range (−40°C to +125°C). It is used in battery-powered voltage monitoring circuits where low quiescent current and ground-sensing capability are critical.
For engineers reviewing the LMV339IPT datasheet, LMV339IPT pinout, LMV339IPT application, or LMV339IPT equivalent, key selection criteria include input offset voltage (1–9 mV), output sink current (10–93 mA), common-mode input range extending to ground, thermal resistance (100 °C/W for TSSOP14), and compatibility with 2.7–5 V single-supply systems.
Technical Context
The LMV339IPT implements four independent high-speed comparators with rail-to-rail input stages and open-drain NMOS outputs, enabling wired-OR logic and level translation. Its input stage operates down to VCC− (ground) and up to VCC+ − 0.3 V, supporting direct sensing of battery voltages and reference thresholds without external biasing.
Propagation delay is optimized for overdrives ≥10 mV, with TPHL = 275 ns and TPLH = 425 ns at 5 V supply and 50 pF load. The device uses internal compensation and exhibits no phase reversal under common-mode transients, making it suitable for precision window detection and power-good signaling.

| 9 | IN3− | Inverting input of Comparator 3 - Fully decoupled from other channels; no crosstalk in typical layout. |
| 10 | IN3+ | Non-inverting input of Comparator 3 - Supports independent reference configuration per channel. |
| 11 | IN4− | Inverting input of Comparator 4 - Final channel for quad monitoring (e.g., overvoltage, undervoltage, temp, status). |

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 |
|---|---|---|---|
| TLV339IPWR | Lower ICC (12 µA typ), but higher VIO (3–12 mV); TSSOP14, same pinout. | Superior battery life in ultra-low-power sleep modes; less precise thresholding at cold temperatures. | Select when quiescent current dominates design priority and ±12 mV offset is acceptable. |
| LM339DT | Wider supply range (2–36 V), higher ICC (500 µA), SO14 package, not rail-to-rail input. | Compatible with legacy 12 V/24 V industrial systems; requires input biasing for ground-referenced signals. | Select for retrofit designs requiring backward compatibility with LM339 footprint and voltage headroom. |
Compared with TLV339IPWR, LMV339IPT trades 13 µA lower ICC for tighter offset and better cold-temperature drift; compared with LM339DT, it reduces supply current by 95% and eliminates input bias networks-critical for modern compact battery-powered systems.

FAQ
What is the maximum sink current per output of the LMV339IPT?
Each open-drain output can sink up to 93 mA at VCC = 5 V and TAMB = +25°C, with guaranteed minimum of 10 mA across −40°C to +125°C. This allows direct driving of LEDs, small relays, or logic inputs without external buffers, provided PCB traces and pull-up resistors are rated accordingly.
Does the LMV339IPT require external pull-up resistors on its outputs?
Yes - all four outputs are open-drain NMOS structures and must be pulled up to a valid logic-high voltage (e.g., 1.8 V, 3.3 V, or 5 V) using external resistors. Typical values range from 2.2 kΩ to 10 kΩ depending on speed and current requirements; no internal pull-ups are present.
Can the LMV339IPT operate with a 2.5 V supply?
No - the absolute minimum supply voltage is 2.7 V per datasheet Section 2 (Operating Conditions). Operation below 2.7 V is not characterized or guaranteed; input common-mode range and propagation delay degrade unpredictably, and output saturation may fail to meet specification.
Is the LMV339IPT pin-compatible with the LM339DT in SO14 packages?
No - while both are quad comparators in 14-pin packages, LMV339IPT uses TSSOP14 with 0.65 mm pitch and different pin mapping (e.g., VCC+ on pin 14, VCC− on pin 7), whereas LM339DT uses SO14 with 1.27 mm pitch and VCC+ on pin 16 (SO16) or pin 4 (SO14 variant). Footprint and signal routing are incompatible.
