Product details
Overview
LMV7219M5 from Texas Instruments is a single-channel, rail-to-rail output comparator optimized for high-speed, low-power applications. It delivers 7 ns propagation delay at 5 V supply, draws only 1.1 mA quiescent current, and supports input common-mode voltage down to −0.2 V (200 mV below ground), enabling ground-sensing in portable battery-powered systems.
For engineers reviewing the LMV7219M5 datasheet, LMV7219M5 pinout, LMV7219M5 application, or LMV7219M5 equivalent, key selection criteria include propagation delay vs. supply current trade-off, internal hysteresis value (7.5 mV typ. at 5 V), rail-to-rail push-pull output drive capability, and SC-70-5 package compatibility with space-constrained PCB layouts.
Technical Context
The LMV7219M5 employs a PNP-input differential stage enabling extended common-mode range below ground, with input bias current flowing *out* of both inputs. Its internal 7.5 mV hysteresis is stable across 2.7–5 V supply and −40°C to +85°C ambient temperature, eliminating need for external hysteresis resistors in noise-prone zero-crossing or threshold detection.
It features a push-pull output stage delivering 30 mA sink/source capability at 5 V, with fast 1.3 ns rise and 1.25 ns fall times into 10 pF load. Propagation delay skew is tightly controlled at 0.4 ns (typ.), ensuring consistent timing in differential signaling paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 7 ns (typ. at 5 V, 50 mV overdrive) - enables sampling of >100 MHz signals with deterministic timing |
| Supply Current | 1.1 mA (typ. at 5 V) - supports battery life extension in always-on sensing nodes |
| Input Common-Mode Range | −0.2 V to VCC−1.2 V - allows direct ground-referenced input monitoring without level-shifting |
| Output Drive | Rail-to-rail push-pull, ±30 mA (min. sink/source at 5 V) - drives 50-Ω transmission lines or logic inputs directly |
| Internal Hysteresis | 7.5 mV (typ. at 5 V) - suppresses chatter on slow-moving or noisy inputs without external components |
| Input Offset Voltage | 6 mV (max. over temp) - ensures reliable trip-point accuracy in precision threshold detection |
| Operating Supply | 2.7 V to 5 V - compatible with Li-ion, 3.3 V, and 5 V system rails without regulators |
Pinout & Package
LMV7219M5 is packaged in SC-70-5 (DCK), measuring 2.00 mm × 1.25 mm, with 0.65 mm lead pitch and exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Push-pull rail-to-rail CMOS-compatible output; sinks or sources up to 30 mA |
| 2 (V−) | Negative Supply | Ground reference for single-supply operation; accepts 0 V or negative voltage in split-supply mode |
| 3 (+IN) | Non-inverting Input | PNP-based input with bias current flowing *out*; supports −0.2 V to VCC−1.2 V common-mode range |
| 4 (−IN) | Inverting Input | Identical PNP structure to +IN; differential pair enables precise voltage comparison |
| 5 (V+) | Positive Supply | Accepts 2.7–5 V; powers internal bias network and output stage |
Key Features
| Feature | Design Value |
|---|---|
| 7 ns propagation delay at 5 V | Enables real-time response in high-speed data acquisition and clock recovery circuits |
| Internal 7.5 mV hysteresis | Eliminates external feedback resistors in window comparators and zero-crossing detectors |
| Rail-to-rail push-pull output | Drives TTL/CMOS loads directly without pull-up resistors, reducing BOM count and board area |
| −0.2 V input common-mode range | Permits direct connection to ground-referenced sensors (e.g., current shunts, thermocouples) |
| SC-70-5 package | Reduces footprint by >40% vs. SOT-23-5, critical for ultra-compact wearables and IoT edge nodes |

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 resistors; higher power limits use in always-on battery systems | Preferred when lowest possible delay is critical and board space allows hysteresis components |
| MAX961ESA+ | 4.5 ns delay, 5.5 mA supply current, 2 mV hysteresis, SO-8 package | Larger footprint; higher current draw restricts use in energy-harvesting designs | Chosen for ultra-high-speed applications where 4.5 ns timing margin outweighs power penalty |
Compared with TLV3501DBVR and MAX961ESA+, the LMV7219M5 offers optimal balance of speed (7 ns), ultra-low power (1.1 mA), integrated hysteresis, and miniature SC-70 packaging-making it uniquely suited for size- and battery-constrained high-speed sensing.

FAQ
What is the maximum operating junction temperature for the LMV7219M5?
The LMV7219M5 has a maximum junction temperature of 125°C, with thermal metrics specifying RθJA = 296°C/W for the SC-70-5 (DCK) package. This allows continuous operation at +85°C ambient when PCB temperature remains ≤105°C, as confirmed in Section 6.3 of the datasheet.
Does the LMV7219M5 require external hysteresis resistors for stable operation?
No, the LMV7219M5 integrates 7.5 mV of internal hysteresis (typ. at 5 V), which eliminates the need for external hysteresis resistors in most zero-crossing, threshold, and window comparator applications. This is explicitly stated in the Features and Detailed Description sections of the LMV7219M5 datasheet.
Can the LMV7219M5 operate from a 2.7-V single supply?
Yes, the LMV7219M5 is fully specified for 2.7 V to 5 V single-supply operation. At 2.7 V, it maintains 12 ns propagation delay (typ.), 0.9 mA supply current (typ.), and retains full rail-to-rail output swing and −0.2 V input common-mode range, per Electrical Characteristics Table 6.5.
What is the output drive capability of the LMV7219M5 at 5 V supply?
At 5 V supply, the LMV7219M5 delivers ±30 mA minimum output current (sourcing and sinking), with rail-to-rail swing: high-level output reaches VCC−0.13 V (typ.) at 0.4 mA load, and low-level output drops to 80 mV (typ.) at −4 mA sink current, as verified in Table 6.6 of the LMV7219M5 datasheet.
Is the LMV7219M5 pin-compatible with other SC-70-5 comparators like the TLV3501?
No, the LMV7219M5 is not pin-compatible with the TLV3501DBVR. While both use SC-70-5 packages, their pinouts differ: LMV7219M5 assigns Pin 1 to OUT, Pin 2 to V−, Pin 3 to +IN, Pin 4 to −IN, Pin 5 to V+; TLV3501 uses Pin 1 to V+, Pin 2 to −IN, Pin 3 to +IN, Pin 4 to OUT, Pin 5 to GND - requiring PCB layout revision for substitution.
