Product details
Overview
LMV7219M7/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 - designed for high-speed threshold detection in portable battery-powered systems.
For engineers reviewing the LMV7219M7/NOPB datasheet, LMV7219M7/NOPB pinout, LMV7219M7/NOPB application, or LMV7219M7/NOPB equivalent, key selection criteria include propagation delay vs. supply current trade-off, internal hysteresis value (7.5 mV at 5 V), rail-to-rail push-pull output drive capability, and SC-70 package suitability for space-constrained PCB layouts.
Technical Context
The LMV7219M7/NOPB employs a PNP-input differential stage enabling ground-sensing operation and delivering consistent 7 ns propagation delay across 2.7–5 V supply range. Its internal 7.5 mV hysteresis eliminates external feedback components while ensuring clean switching with slow-moving inputs.
It features a push-pull output stage that provides fast rise/fall times (1.3 ns/1.25 ns at 5 V) and supports sourcing/sinking up to 68 mA/65 mA, with thermal design validated for 105°C PCB temperature and 125°C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV7235M5/NOPB | Lower supply current (650 µA), slower propagation delay (12 ns), same SC-70 package | Better suited for ultra-low-power wake-up detection where speed is secondary | Select when <1 µA quiescent current is critical and 12 ns delay is acceptable |
| TLV3501DBVR | Faster propagation delay (4.5 ns), higher supply current (5.5 mA), SOT-23-6 package | Requires external hysteresis; lacks ground-sensing input range | Select when sub-5 ns timing is mandatory and board space allows SOT-23-6 |
Compared with LMV7219M7/NOPB, LMV7235M5/NOPB trades speed for lower power, while TLV3501DBVR offers higher speed at significantly increased current and no built-in hysteresis - making LMV7219M7/NOPB optimal for balanced high-speed, low-power, component-minimized designs.

FAQ
What is the maximum operating supply voltage for LMV7219M7/NOPB?
The absolute maximum supply voltage (V+ − V−) for LMV7219M7/NOPB is 5.5 V. The recommended operating range is 2.7 V to 5 V. Operation above 5.5 V risks permanent damage to the input stage, especially given its PNP-based architecture. For reliable long-term use, maintain supply within the 2.7–5 V range specified in the Electrical Characteristics tables of the LMV7219M7/NOPB datasheet.
Does LMV7219M7/NOPB require external hysteresis resistors?
No, LMV7219M7/NOPB integrates 7.5 mV of internal hysteresis at 5 V, eliminating the need for external positive feedback resistors in most threshold-detection applications. This simplifies PCB layout and improves system reliability. External hysteresis can be added via three-resistor networks if wider hysteresis bands (>100 mV) are required, but the LMV7219M7/NOPB's built-in hysteresis suffices for noise suppression in standard zero-crossing and window comparator designs.
What is the input bias current direction and magnitude for LMV7219M7/NOPB?
The LMV7219M7/NOPB uses a PNP-input stage, so input bias current flows *out* of both +IN and −IN pins. Typical input bias current is 500–950 nA at 5 V and 25°C, rising to ≤2000 nA over full temperature range. This outward current flow must be accounted for in high-impedance source networks, as it creates a voltage drop across source resistance that affects trip-point accuracy - particularly critical in precision threshold detection using the LMV7219M7/NOPB.
Can LMV7219M7/NOPB operate with inputs below ground?
Yes, LMV7219M7/NOPB supports an input common-mode voltage range extending to −0.2 V (at 25°C) relative to V−, enabling true ground-sensing functionality in single-supply configurations. This allows direct connection of one input to system ground while detecting signals referenced to that same ground - a key enabler for zero-crossing detectors and battery-monitoring circuits. Operation below −0.2 V risks forward-biasing substrate junctions and increasing input bias current unpredictably.
What package type is used for LMV7219M7/NOPB and what are its dimensions?
LMV7219M7/NOPB is supplied in the SC-70 (DCK) package, a 5-pin surface-mount outline measuring 2.00 mm × 1.25 mm with a maximum height of 0.9 mm. This compact footprint is ideal for space-constrained applications like portable scanners and set-top box front panels. The SC-70 package shares pin compatibility with other members of the LMV72xx family but is distinct from the larger SOT-23 (DBV) variant also offered for the LMV7219 series.
