Product details
Overview
LMV7239QM7X/E7002934 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified ultra-low-power rail-to-rail input comparator with 75 ns propagation delay, 65 µA supply current at 5 V, and dual-output capability (open-drain + push-pull) for flexible interface design in battery-constrained systems.
For engineers reviewing the LMV7239QM7X/E7002934 datasheet, LMV7239QM7X/E7002934 pinout, LMV7239QM7X/E7002934 application, or LMV7239QM7X/E7002934 equivalent, key selection considerations include its −40°C to +125°C operating range, 2.7–5.5 V single-supply operation, rail-to-rail input extending 200 mV beyond rails, and push-pull output eliminating external pull-up requirements.
Technical Context
The LMV7239QM7X/E7002934 employs a complementary PNP/NPN input stage enabling > rail-to-rail common-mode range (−0.2 V to VCC + 0.2 V), supporting ground- and supply-referenced sensing. Its push-pull output delivers fast 1.2 ns fall time (5 V, 15 pF) without external biasing.
Propagation delay remains stable across temperature (80–96 ns at −40°C to +125°C, 5 V, 20 mV overdrive) and load capacitance (75–106 ns, 0–100 pF), with minimal sensitivity to resistive loading on the falling edge-enabling reliable timing in high-speed sampling and zero-crossing detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 75 ns @ 5 V, 100 mV overdrive, 15 pF - enables sub-13 MHz sampling rate in comparator-based ADC front-ends |
| Supply Current | 65 µA @ 5 V, 25°C - supports multi-year operation in coin-cell-powered automotive sensors |
| Input Common-Mode Range | −0.2 V to VCC + 0.2 V - allows direct sensing of signals below ground or above supply (e.g., battery voltage monitoring) |
| Output Type | Push-pull + open-drain selectable - eliminates need for external pull-up resistor in most logic interfacing |
| Supply Voltage Range | 2.7 V to 5.5 V - compatible with 3.3 V and 5 V microcontroller I/O domains and automotive 12 V system rails via LDO |
| Input Offset Voltage | ±1 mV @ 5 V, 25°C - ensures ≤10 mV trip-point error in precision window detectors |
| ESD Rating | HBM ±1000 V, CDM ±750 V (DBV package) - meets AEC-Q100 stress requirements for under-hood electronics |
Pinout & Package
LMV7239QM7X/E7002934 is packaged in a 5-pin SC70 (DGK) with nominal body size 2.00 mm × 1.25 mm, optimized for space-constrained automotive modules and portable instrumentation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7239QDR | Same architecture, 5-pin SOIC package (3.9 mm × 4.9 mm); 70 ns delay, 75 µA IQ at 5 V | Larger footprint; higher thermal resistance (RθJA = 132°C/W vs. 478°C/W for SC70); suited for prototyping or non-space-constrained modules | Select when board layout allows SOIC and thermal margin exceeds 40°C/W requirement |
| LMV7219QMF/NOPB | SC70-5 variant with identical specs but non-automotive grade (no AEC-Q100); same 75 ns/65 µA performance | Not qualified for automotive use; suitable for industrial or medical portable devices requiring same speed/power | Choose for cost-sensitive non-automotive designs where AEC-Q100 is not mandated |
Compared with TLV7239QDR and LMV7219QMF/NOPB, LMV7239QM7X/E7002934 uniquely combines AEC-Q100 Grade 1 qualification, SC70 packaging, and 75 ns/65 µA performance-making it the only option for production automotive systems demanding both miniaturization and functional safety compliance.

FAQ
What is the maximum operating temperature for LMV7239QM7X/E7002934?
The LMV7239QM7X/E7002934 is AEC-Q100 Grade 1 qualified with a guaranteed operating ambient temperature range of −40°C to +125°C. Junction temperature must not exceed 150°C; derating applies above 85°C ambient depending on PCB thermal design and power dissipation. This rating is validated per TI's production test flow and documented in SNOSD85 Rev. A.
Does LMV7239QM7X/E7002934 support true rail-to-rail input operation?
Yes, LMV7239QM7X/E7002934 supports greater-than-rail-to-rail input: the common-mode voltage range extends from −0.2 V to VCC + 0.2 V, verified across temperature and supply voltage (2.7–5.5 V). This allows direct sensing of signals below ground (e.g., shunt current monitor returns) and above supply (e.g., battery voltage pre-LDO), as confirmed in Section 6.5 and 6.6 of the SNOSD85 datasheet.
Can LMV7239QM7X/E7002934 drive a 15-pF capacitive load with stable 75 ns propagation delay?
Yes, LMV7239QM7X/E7002934 maintains 75 ns propagation delay (typical) with 15 pF load at 5 V supply and 100 mV input overdrive, as specified in Table 6.6. Figure 10 and 11 confirm delay stability across 0–100 pF loads, and layout guidelines (Section 10) require short traces and local 0.1 µF ceramic decoupling to preserve this performance.
Is LMV7239QM7X/E7002934 pin-compatible with standard SC70-5 comparators like TLV3701?
No, LMV7239QM7X/E7002934 is not pin-compatible with TLV3701 or other SC70-5 comparators. Its pin 1 is VOUT, pin 2 is V−, pin 3 is IN+, pin 4 is IN−, and pin 5 is V+ - a fixed assignment per Figure 5 in SNOSD85. TLV3701 uses different pinout (e.g., IN− on pin 2), so PCB redesign is required for substitution.
What output configuration does LMV7239QM7X/E7002934 use by default?
LMV7239QM7X/E7002934 features an integrated push-pull output stage as the primary configuration, enabling direct TTL/CMOS interfacing without external pull-up resistors. The device also supports open-drain operation via internal configuration - no external components needed. This dual-mode capability is explicitly stated in the title and Features section of SNOSD85 Rev. A.
