Product details
Overview
LMV7219M5/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 LMV7219M5/NOPB datasheet, LMV7219M5/NOPB pinout, LMV7219M5/NOPB application, or LMV7219M5/NOPB 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 LMV7219M5/NOPB employs a PNP-input differential stage enabling −0.2 V to VCC−1.2 V input common-mode range and outward-flowing input bias current (500–950 nA). Its internal 7.5 mV hysteresis eliminates external feedback resistors while ensuring clean transitions for slow-moving inputs.
It features a push-pull output stage delivering 30 mA sink/source capability at 5 V, with rise/fall times of 1.3 ns/1.25 ns and propagation delay skew under 0.4 ns - optimized for high-speed sampling, zero-crossing detection, and differential line reception where timing precision and noise immunity are critical.
Key Specifications

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, 2.9 mA supply current, no internal hysteresis, same SC-70-5 package | Requires external hysteresis resistors; higher power limits use in always-on sensing nodes | Select when absolute minimum delay is prioritized and board space allows for two external resistors |
| MAX961ASA+ | 4.5 ns propagation delay, 5.5 mA supply current, 3 mV hysteresis, SO-8 package (larger footprint) | Higher speed but 5× higher quiescent current; SO-8 requires more PCB area and has higher RθJA | Select only when sub-5 ns timing is mandatory and thermal budget permits higher power dissipation |
Compared with TLV3501DBVR and MAX961ASA+, the LMV7219M5/NOPB uniquely balances 7 ns speed, 1.1 mA supply current, integrated hysteresis, and SC-70-5 size - making it optimal for space- and power-sensitive high-speed threshold detection where external component count must be minimized.

FAQ
What is the maximum operating supply voltage for LMV7219M5/NOPB?
The LMV7219M5/NOPB has an absolute maximum supply voltage (V+ − V−) of 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 if differential input voltage exceeds supply rails. For reliable long-term use, maintain supply within 2.7–5.0 V per the Electrical Characteristics tables in the datasheet.
Does LMV7219M5/NOPB require external hysteresis resistors?
No, the LMV7219M5/NOPB includes 7.5 mV typical internal hysteresis, eliminating the need for external positive-feedback resistors in most threshold-detection applications. This simplifies design and reduces component count. External hysteresis can be added via three-resistor networks if wider bands (>200 mV) are required, as detailed in Section 8.2.2.1 of the LMV7219M5/NOPB datasheet.
Can LMV7219M5/NOPB operate with input voltages below ground?
Yes, the LMV7219M5/NOPB input common-mode range extends to −0.2 V (200 mV below ground) at 25°C, enabling true ground-sensing functionality in single-supply configurations. This is confirmed in Sections 6.5 and 6.6 of the datasheet. Operation below −0.2 V may increase input bias current due to parasitic junction conduction but does not damage the device within Absolute Maximum Ratings.
What is the output drive capability of LMV7219M5/NOPB at 5 V supply?
At 5 V supply, the LMV7219M5/NOPB delivers up to 30 mA sink current and 68 mA source current into short-circuit conditions (per Section 6.6). Under normal load, it drives 4 mA with VO(H) ≥ 4.87 V and VO(L) ≤ 180 mV. The push-pull architecture ensures fast switching without external pull-ups, supporting direct interfacing with 3.3 V or 5 V logic families.
Which package does LMV7219M5/NOPB use, and is it RoHS-compliant?
The LMV7219M5/NOPB uses the SC-70-5 (DCK) package - 2.00 mm × 1.25 mm body with 0.65 mm lead pitch. It is RoHS-compliant and lead-free, as indicated by the "/NOPB" suffix per TI's packaging nomenclature. Thermal resistance is RθJA = 296°C/W, and the device supports reflow soldering per JEDEC J-STD-020 moisture sensitivity level 1.
