Product details
Overview
LMV7275MF/NOPB from Texas Instruments is a single-channel, rail-to-rail input, low-power comparator with open-drain output, designed for 1.8-V to 5.5-V operation. It delivers 9 µA supply current per channel, 4 mV max input offset voltage, and 880 ns propagation delay (20-mV overdrive at 1.8 V), enabling precision threshold detection in battery-powered wearables and portable electronics.
For engineers reviewing the LMV7275MF/NOPB datasheet, LMV7275MF/NOPB pinout, LMV7275MF/NOPB application, or LMV7275MF/NOPB equivalent, key selection considerations include its open-drain output enabling wired-OR logic and level-shifting up to 5.5 V, ultra-low quiescent current for multi-year battery life, rail-to-rail input extending common-mode range beyond rails, and SC70-5 package for space-constrained PCB layouts.
Technical Context
The LMV7275MF/NOPB uses a paralleled PNP/NPN bipolar input stage to achieve −0.1 V to V+ + 0.1 V input common-mode range, with crossover-induced VOS variation near mid-supply. Its open-drain NMOS output stage eliminates internal pull-up, requiring external pull-up for logic-level translation across voltage domains.
Unlike the push-pull LMV7271/LMV7272, the LMV7275MF/NOPB's output rise time depends on external RC load, while fall time remains fast and supply-voltage-independent. It supports single or dual supply operation, with guaranteed functionality from −40°C to +85°C and ESD robustness of ±2000 V HBM.

Pinout & Package
LMV7275MF/NOPB is packaged in SC70-5 (1.25 mm × 2.00 mm), a surface-mount, lead-free, RoHS-compliant package optimized for high-density portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN | Noninverting Input | Differential input node accepting signals from −0.1 V to V+ + 0.1 V; bipolar input structure ensures low noise and stable bias current |
| GND | Negative Supply Terminal | Reference return path for supply and input common-mode; must be low-impedance to minimize ground bounce in open-drain switching |
| −IN | Inverting Input | Differential input node with identical common-mode range as +IN; used for threshold comparison or zero-crossing detection |
| VOUT | Open-Drain Output | NMOS drain terminal requiring external pull-up; enables level-shifting, wired-OR logic, and interface to 1.2–5.5 V digital buses |
| V+ | Positive Supply Terminal | Primary power input (1.8–5.5 V); bypass capacitor (0.1 µF) required adjacent to pin to suppress shoot-through transients |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211DBVR | Push-pull output, 11 µA supply current, 1.5 mV max VOS, same SC70-5 package | Lacks open-drain flexibility; requires pull-up for wired-OR; better for driving CMOS loads directly | Select TLV7211DBVR when driving capacitive digital inputs directly without level translation |
| MAX9021AXK+T | Open-drain output, 1 µA supply current, 5 mV max VOS, SC70-5, but only rated to 3.6 V max supply | Lower power but incompatible with 5 V systems; higher VOS reduces margin for tight thresholds | Select MAX9021AXK+T only for sub-3.6 V battery systems where <1 µA sleep current is mandatory |
Compared with TLV7211DBVR and MAX9021AXK+T, LMV7275MF/NOPB uniquely balances ultra-low power (9 µA), wide supply range (1.8–5.5 V), open-drain flexibility, and production-proven reliability-making it optimal for cross-voltage domain monitoring in portable industrial and medical devices.

FAQ
What is the maximum supply voltage rating for LMV7275MF/NOPB?
The absolute maximum supply voltage for LMV7275MF/NOPB is 6 V, but the recommended operating range is 1.8 V to 5.5 V. Operation above 5.5 V risks permanent damage, while operation below 1.8 V may result in degraded propagation delay and increased input offset voltage. All electrical characteristics in the datasheet are specified within the 1.8–5.5 V range, and LMV7275MF/NOPB is fully characterized at 1.8 V, 2.7 V, and 5 V.
Does LMV7275MF/NOPB support dual-supply operation?
Yes, LMV7275MF/NOPB supports dual-supply operation with V+ and V− terminals. The datasheet specifies operation with V− = 0 V (single supply) and also validates performance with split supplies such as ±2.5 V. The input common-mode range extends 0.1 V beyond both rails, allowing inputs to swing from −0.1 V to V+ + 0.1 V - making LMV7275MF/NOPB suitable for bipolar signal conditioning in sensor front-ends.
Why does LMV7275MF/NOPB use an open-drain output instead of push-pull?
LMV7275MF/NOPB uses an open-drain output to enable wired-OR logic, level-shifting across voltage domains (e.g., 1.8-V comparator output pulled to 3.3 V), and compatibility with legacy bus standards like I²C. Unlike the push-pull LMV7271, this architecture avoids shoot-through current and simplifies interfacing where multiple comparators share a single interrupt line - a key requirement in compact portable designs where LMV7275MF/NOPB is commonly deployed.
Can LMV7275MF/NOPB drive a 10-kΩ load directly?
Yes, LMV7275MF/NOPB can drive a 10-kΩ pull-up load effectively. With typical output leakage of only 2 pA, the voltage drop across a 10-kΩ resistor is negligible (<20 nV), ensuring clean logic-high assertion. However, rise time will scale with RC time constant - for example, with 10-kΩ and 10 pF capacitance, rise time is ~100 ns. LMV7275MF/NOPB's fall time remains fast and independent of load, making it well-suited for asymmetric timing requirements in alert and wake-up circuits.
Is LMV7275MF/NOPB pin-compatible with LMV7271MF/NOPB?
No, LMV7275MF/NOPB is not pin-compatible with LMV7271MF/NOPB despite sharing the same SC70-5 package footprint. LMV7271MF/NOPB has a push-pull output connected to pin 4 (VOUT), while LMV7275MF/NOPB uses that same pin 4 as an open-drain output - requiring external pull-up and different routing. Swapping them without board revision will cause functional failure. Always verify pin function mapping using the official TI datasheet for LMV7275MF/NOPB before substitution.
