Product details

Overview

LMV7219M5X from Texas Instruments is a single-channel, rail-to-rail output comparator with 7 ns propagation delay, 1.1 mA supply current at 5 V, and input common-mode range extending 200 mV below ground - enabling ground-sensing in portable battery-powered systems.

For engineers reviewing the LMV7219M5X datasheet, LMV7219M5X pinout, LMV7219M5X application, or LMV7219M5X equivalent, key selection criteria include propagation delay vs. supply current trade-off, internal hysteresis (7.5 mV typ. at 5 V), rail-to-rail push-pull output drive capability, and SC-70-5 package compatibility with high-density PCB layouts.

Technical Context

The LMV7219M5X uses a PNP-input differential stage enabling −0.2 V to V_CC−1.2 V input common-mode range and sourcing/sinking output stage delivering 30 mA short-circuit current. Its fixed internal hysteresis (7.5 mV) eliminates external feedback resistors for noise-immune threshold detection.

Propagation delay remains stable across overdrive levels (7 ns at 50 mV overdrive, 5 V supply) and temperature (−40°C to +85°C ambient), while rise/fall times (1.3 ns / 1.25 ns) support high-speed sampling and zero-crossing detection without external compensation.

Key Specifications

Parameter	Value and Actual Design Meaning
Propagation delay	7 ns at 5 V, 50 mV overdrive - enables sub-100 MHz signal edge detection in timing-critical circuits
Supply current	1.1 mA at 5 V - supports ultra-low-power operation in battery-backed systems
Input common-mode range	−0.2 V to V_CC−1.2 V - allows direct ground-referenced input sensing without level-shifting
Output drive	Rail-to-rail push-pull, 30 mA sink/source - drives 50 Ω transmission lines or logic inputs directly
Hysteresis voltage	7.5 mV typical at 5 V - suppresses chatter on slow-moving or noisy inputs without external components
Input offset voltage	6 mV max at 25°C - ensures accurate threshold detection in precision window comparators
Operating supply	2.7 V to 5 V single supply - compatible with Li-ion, 3.3 V, and 5 V system rails

Pinout & Package

LMV7219M5X is packaged in SC-70-5 (DCK), measuring 2.00 mm × 1.25 mm, optimized for space-constrained portable designs.

Pin/Terminal	Circuit Role	Design Meaning
1 (OUT)	Output	Push-pull rail-to-rail CMOS-compatible output capable of driving 4 mA load with <0.2 V drop
2 (V−)	Negative supply	Ground reference terminal; supports single-supply operation with inputs down to −0.2 V
3 (+IN)	Non-inverting input	PNP-based input accepting signals within full common-mode range; bias current flows out
4 (−IN)	Inverting input	Identical PNP structure to +IN; enables differential or single-ended configurations
5 (V+)	Positive supply	2.7–5 V supply input; decoupling capacitor must be placed ≤0.5 inch away for stability

Key Features

Feature	Design Value
Internal hysteresis	7.5 mV fixed value eliminates need for external positive-feedback resistors in threshold detectors
Rail-to-rail output	Swings within 130 mV of rails at 4 mA load - interfaces directly with 1.8 V/3.3 V logic families
Ground-sensing input	Common-mode range extends 200 mV below V− - enables zero-crossing detection without level shifters
High-speed response	1.3 ns rise / 1.25 ns fall time supports >300 MHz edge rates in sampling circuits
Thermal robustness	Rated for 105°C PCB temperature - suitable for thermally dense handheld and set-top box applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar comparator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV3501DBVR	6.5 ns propagation delay, 2.5 mA supply current, no internal hysteresis	Requires external hysteresis network; higher power draw limits battery life	Preferred when lowest possible delay is critical and board area permits external resistors

FAQ

What is the maximum operating temperature for LMV7219M5X?

The LMV7219M5X is specified for ambient temperatures from −40°C to +85°C and supports PCB temperatures up to 105°C. Its junction temperature limit is 125°C under recommended operating conditions, with thermal metrics (R_θJA = 296°C/W for SC-70) enabling thermal design validation using standard PCB copper area guidelines. The LMV7219M5X maintains full electrical performance within this range.

Does LMV7219M5X require external hysteresis resistors?

No, the LMV7219M5X integrates 7.5 mV of internal hysteresis, eliminating the need for external positive-feedback resistors in most threshold-detection applications. This simplifies layout, reduces component count, and improves reliability. External hysteresis can be added via three-resistor networks if wider bands (>100 mV) are required, but the LMV7219M5X functions robustly out-of-the-box for standard zero-crossing and window-comparator use cases.

Can LMV7219M5X operate from a 2.7 V single supply?

Yes, the LMV7219M5X is fully specified for 2.7 V to 5 V single-supply operation. At 2.7 V, it delivers 12 ns propagation delay (5 mV overdrive), 0.9 mA supply current, and maintains rail-to-rail output swing with 300 mV low-level output voltage under 4 mA load. Its input common-mode range extends to −0.2 V, enabling true ground-referenced sensing even at minimum supply.

What is the output drive capability of LMV7219M5X?

The LMV7219M5X features a push-pull rail-to-rail output stage capable of sourcing and sinking up to 30 mA (typ. at 5 V). Under 4 mA load, output swing is V_CC−0.2 V (high) and 180 mV (low) at 5 V, and V_CC−0.4 V / 300 mV at 2.7 V. This allows direct interfacing with TTL, CMOS, and microcontroller GPIO pins without level-shifting or buffering circuitry - a key advantage of the LMV7219M5X in mixed-voltage systems.

Is LMV7219M5X pin-compatible with other SC-70-5 comparators?

The LMV7219M5X uses standard SC-70-5 (DCK) pinout: Pin 1 = OUT, Pin 2 = V−, Pin 3 = +IN, Pin 4 = −IN, Pin 5 = V+. While physically compatible with other SC-70-5 comparators, functional equivalence requires verification of input stage architecture (PNP vs. NMOS), hysteresis presence, and output drive type. The LMV7219M5X's PNP input and integrated hysteresis distinguish it from many alternatives - always validate behavior in final circuit before substitution.
