Product details
Overview
LMV7219M5X/NOPB 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/NOPB datasheet, LMV7219M5X/NOPB pinout, LMV7219M5X/NOPB application, or LMV7219M5X/NOPB equivalent, key selection criteria include internal hysteresis (7.5 mV), fast rise/fall times (1.3 ns / 1.25 ns), operation from 2.7 V to 5 V, and SC-70-5 package compatibility for space-constrained PCB layouts.
Technical Context
The LMV7219M5X/NOPB uses a PNP-input differential stage enabling −0.2 V to VCC−1.3 V input common-mode range and sourcing/sinking push-pull output architecture. Its internal 7.5 mV hysteresis eliminates external feedback components while ensuring clean transitions on slow-moving inputs.
Propagation delay remains stable across overdrive levels (7 ns at 50 mV overdrive, 9 ns at 5 mV) and temperature (−40°C to +85°C ambient, 105°C PCB). The device supports both single-supply (2.7 V–5 V) and split-supply operation without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 7 ns at 5 V, 50 mV overdrive - enables timing-critical sampling and zero-crossing detection in high-speed digital interfaces. |
| Supply current | 1.1 mA at 5 V - supports low-power operation in battery-backed systems without sacrificing speed. |
| Input common-mode range | −0.2 V to VCC−1.3 V - allows direct ground-referenced signal comparison and eliminates level-shifting circuitry. |
| Output drive | Rail-to-rail push-pull, sinking 65 mA / sourcing 68 mA at 5 V - drives heavy capacitive loads or logic inputs directly. |
| Hysteresis voltage | 7.5 mV - suppresses noise-induced chatter on near-threshold signals without requiring external resistors. |
| Rise/fall time | 1.3 ns / 1.25 ns (10%–90%) - maintains signal integrity in >100 MHz edge-rate applications like crystal oscillators and IR receivers. |
| ESD rating | ±2000 V HBM - ensures robust handling during automated assembly and field deployment. |
Pinout & Package
LMV7219M5X/NOPB is packaged in SC-70-5 (DCK), measuring 2.00 mm × 1.25 mm - optimized for ultra-compact portable electronics and high-density PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output | Push-pull rail-to-rail CMOS-compatible output capable of driving 4 mA load with <300 mV low-level swing at 5 V. |
| 2 (V−) | Negative supply | Ground reference terminal; supports single-supply operation down to 0 V and split-supply configurations. |
| 3 (+IN) | Non-inverting input | PNP-based input accepting signals as low as −0.2 V; bias current flows *out* of this pin (typ. 500–950 nA). |
| 4 (−IN) | Inverting input | Complementary PNP input with identical common-mode and bias characteristics as +IN. |
| 5 (V+) | Positive supply | Accepts 2.7 V–5 V DC; decoupling capacitor must be placed ≤0.5 inch from this pin to maintain 7 ns timing accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Internal hysteresis | 7.5 mV fixed hysteresis eliminates need for external positive-feedback resistors in threshold detectors and window comparators. |
| Rail-to-rail output | Swings within 130 mV of V− and 130 mV of V+ at 4 mA load - interfaces directly with 1.8 V, 3.3 V, and 5 V logic families. |
| Ground-sensing input | Input common-mode extends 200 mV below V− - enables accurate zero-crossing detection and battery-voltage monitoring without offset circuitry. |
| Low-noise propagation | 0.4 ns propagation delay skew (|tPDLH − tPDHL|) ensures symmetrical switching in clock recovery and phase-aligned sampling circuits. |
| Thermal robustness | Rated for 105°C PCB temperature and 125°C junction temperature - suitable for sealed enclosures and automotive cabin environments. |
Applications
| Portable Power Monitoring | High-Speed Crystal Oscillator |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3501DBVR | 1.5 ns propagation delay, 2.5 mA supply current, no internal hysteresis - requires external feedback network. | Better suited for sub-ns timing-critical ADC triggering where hysteresis is added externally for precision control. | Select when absolute minimum delay outweighs board area and design complexity trade-offs. |
| MAX961ASA+ | 4.5 ns delay, 2.1 mA supply current, 2.7 V–5.5 V operation, integrated 2 mV hysteresis - smaller hysteresis than LMV7219M5X/NOPB. | Preferred for low-jitter clock regeneration where tighter hysteresis tolerance reduces timing uncertainty in PLL loops. | Choose when system-level noise margin permits lower hysteresis and higher supply current is acceptable. |
Compared with TLV3501DBVR and MAX961ASA+, the LMV7219M5X/NOPB offers optimal balance of speed (7 ns), ultra-low power (1.1 mA), and fixed internal hysteresis (7.5 mV) - reducing BOM count and layout sensitivity in portable and industrial sensing applications.

FAQ
What is the maximum PCB temperature rating for LMV7219M5X/NOPB?
The LMV7219M5X/NOPB is rated for continuous operation at up to 105°C PCB temperature, as confirmed in Section 6.3 of the official datasheet. This specification supports use in thermally demanding environments such as enclosed industrial enclosures and automotive cabin modules, provided junction temperature remains ≤125°C under actual operating conditions.
Does LMV7219M5X/NOPB require external hysteresis resistors?
No, LMV7219M5X/NOPB integrates 7.5 mV of internal hysteresis, eliminating the need for external positive-feedback resistors in standard threshold and window comparator configurations. External hysteresis can be added only if wider bands (>100 mV) are required, using the three-resistor method described in Section 8.2.2.1 of the datasheet.
Can LMV7219M5X/NOPB operate from a 2.7-V single supply?
Yes, LMV7219M5X/NOPB 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), 0.9–2.2 mA supply current, and maintains rail-to-rail output swing - making it ideal for coin-cell and Li-ion powered systems where supply headroom is constrained.
What package type does LMV7219M5X/NOPB use?
LMV7219M5X/NOPB uses the SC-70-5 (DCK) package, measuring 2.00 mm × 1.25 mm with 0.65 mm pitch. This ultra-small outline package is distinct from the SOT-23-5 variant (DBV) and is optimized for high-density portable PCBs where board space is at a premium.
How does the input bias current direction affect circuit design for LMV7219M5X/NOPB?
LMV7219M5X/NOPB features PNP-input transistors, causing input bias current to flow *out* of both +IN and −IN pins (typ. 500–950 nA). This requires source impedances to be kept low (<10 kΩ) to avoid offset errors, and pull-up/pull-down networks must account for net current draw rather than injection - especially critical in high-impedance sensor interfaces.
