Product details
Overview
LMV7239QM7/NOPB from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified, ultra-low-power, rail-to-rail input comparator with push-pull output. It delivers 75 ns propagation delay at 5 V, consumes only 65 µA supply current, and operates across 2.7 V to 5.5 V supply range - enabling use in battery-powered ADAS sensors and low-voltage microcontroller wake-up circuits.
For engineers reviewing the LMV7239QM7/NOPB datasheet, LMV7239QM7/NOPB pinout, LMV7239QM7/NOPB application, or LMV7239QM7/NOPB equivalent, key selection criteria include its extended common-mode range (−0.2 V to VCC + 0.2 V), absence of external pull-up requirement, and guaranteed performance from −40°C to +125°C ambient.
Technical Context
The LMV7239QM7/NOPB employs a complementary PNP/NPN input stage enabling true rail-to-rail input operation with common-mode voltage extending 200 mV beyond both supply rails. Its push-pull output stage provides active high/low drive without external biasing, eliminating pull-up resistor dependency and reducing board area in space-constrained modules.
Propagation delay remains stable across capacitive loads up to 15 pF and overdrive voltages ≥20 mV, while input offset voltage is tightly specified at ±1 mV (typ) at 5 V - critical for precision threshold detection in automotive window comparators and zero-crossing detectors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV7235M5/NOPB | Open-drain output requiring external pull-up; 70 ns propagation delay; same supply current and temperature grade | Requires additional resistor for logic-level translation; less suitable for driving CMOS inputs directly | Select when interfacing with open-collector buses or needing wired-OR functionality |
| TLV3604DBVR | 32 ns propagation delay; 85 µA supply current; rail-to-rail input but no extended common-mode range (0 V to VCC) | Higher speed but higher power; lacks ground-below capability for chassis-referenced sensing | Select when nanosecond timing dominates over ultra-low power and extended input range |
Compared with LMV7239QM7/NOPB, LMV7235M5/NOPB trades push-pull simplicity for open-drain flexibility, while TLV3604DBVR prioritizes speed over power and input range - making LMV7239QM7/NOPB optimal for automotive battery monitoring and wake-up circuits demanding low IQ, wide VCM, and robust output drive.

FAQ
What is the maximum capacitive load the LMV7239QM7/NOPB can drive while maintaining 75 ns propagation delay?
The LMV7239QM7/NOPB maintains its specified 75 ns propagation delay (at 100 mV overdrive) up to 15 pF capacitive load, as confirmed in Section 6.6 of the SNOSD85 datasheet. Beyond 15 pF, delay increases gradually due to output stage slew limitations - for loads >20 pF, design validation with actual PCB parasitics is recommended. The LMV7239QM7/NOPB's push-pull output ensures consistent rise/fall times even under moderate capacitive loading.
Does the LMV7239QM7/NOPB require external hysteresis for stable operation with slow-moving input signals?
Yes - the LMV7239QM7/NOPB has high gain (>100 dB) but no internal hysteresis. When input signals transition slowly near the threshold (e.g., thermistor-based temperature monitoring), external positive feedback is required to prevent multiple output toggles. Section 7.4.3 of the datasheet details resistor networks for both inverting and non-inverting hysteresis configurations. The LMV7239QM7/NOPB's rail-to-rail input simplifies hysteresis network design across full supply range.
Can the LMV7239QM7/NOPB operate from a 2.7 V single supply while maintaining full input common-mode range?
Yes - the LMV7239QM7/NOPB is fully specified from 2.7 V to 5.5 V. At 2.7 V supply, its input common-mode range extends from −0.2 V to +2.9 V (VCC + 0.2 V), satisfying the "greater than rail-to-rail" specification. This enables direct interface with 2.5 V reference sources and ground-referenced sensors without level-shifting. All key parameters including propagation delay and supply current remain guaranteed across this range per Section 6.3.
How does the LMV7239QM7/NOPB's push-pull output differ from open-drain comparators in practical circuit design?
The LMV7239QM7/NOPB's push-pull output actively drives both logic high and low states, eliminating the need for an external pull-up resistor required by open-drain comparators like the LMV7235. This reduces component count, saves PCB area, and ensures matched rise/fall times - critical in timing-sensitive applications such as crystal oscillators and sampling triggers. The LMV7239QM7/NOPB can sink/source ≥4 mA, supporting direct connection to standard CMOS inputs without signal degradation.
Is the LMV7239QM7/NOPB pin-compatible with other members of the LMV72xx-Q1 family?
No - the LMV7239QM7/NOPB uses a 5-pin SC70 (DGK) package with pinout VOUT, V−, IN+, IN−, V+. Other variants like LMV7235M5/NOPB share identical pinout and package, but LMV7236 (dual) and LMV7237 (quad) use different pin counts and arrangements. Always verify mechanical compatibility using TI's orderable addendum - the LMV7239QM7/NOPB is not a drop-in replacement for non-single-channel variants despite functional similarity.
