Product details
Overview
LMV393MM/NOPB from Texas Instruments is a dual, low-voltage, open-collector comparator IC designed for space-constrained, battery-powered systems. It operates from 2.7 V to 5 V, draws only 100 µA total supply current (50 µA/channel), features 200 mV output saturation voltage at 4 mA sink, and delivers 200 ns propagation delay at 5 V with 100 mV overdrive - enabling precise threshold detection in portable power management circuits.
For engineers reviewing the LMV393MM/NOPB datasheet, LMV393MM/NOPB pinout, LMV393MM/NOPB application, or LMV393MM/NOPB equivalent, key selection considerations include its ground-sensing input range (−0.1 V to 4.2 V at 5 V), industrial temperature rating (−40°C to +85°C), SOIC-8/VSSOP-8 package compatibility, and open-collector output requiring external pull-up for wired-OR logic or level translation.
Technical Context
The LMV393MM/NOPB implements two independent comparators with bipolar input stages and NPN open-collector outputs, fabricated using TI's Submicron Silicon-Gate BiCMOS process for improved noise immunity versus CMOS-only designs. Its input common-mode range extends 0.1 V below ground and up to 0.8 V below V+, enabling direct sensing of signals referenced to system ground.
Each channel operates with rail-to-rail input capability and delivers fast, predictable switching: propagation delay is specified at 200 ns (typ) under 100 mV overdrive at 5 V, and output saturation remains ≤400 mV (max) at 4 mA sink current. The device supports single-supply operation down to 2.7 V without performance degradation.

Pinout & Package
LMV393MM/NOPB is packaged in an 8-pin VSSOP (DGK) body measuring 3.00 mm × 3.00 mm - a space-saving alternative to standard SOIC-8 with identical pinout and thermal performance (θJA = 23°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 | −IN A | Inverting input for Channel A - typically connected to stable reference voltage or resistor divider |
| 3 | OUT A | Open-collector output for Channel A - requires external pull-up resistor (1–10 kΩ) to V+ or another logic rail |
| 4 | V− | Negative supply terminal - tied to system ground in single-supply configurations |
| 5 | V+ | Positive supply terminal - accepts 2.7 V to 5 V; powers both comparator channels |
| 6 | −IN B | Inverting input for Channel B - electrically isolated from Channel A; supports independent reference setup |
| 7 | +IN B | Noninverting input for Channel B - identical input characteristics to Pin 1 |
| 8 | OUT B | Open-collector output for Channel B - enables independent or wired-OR logic with OUT A |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual open-collector comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Higher supply current (500 µA typ), wider supply range (2–36 V), slower propagation (1.3 µs typ), no guaranteed 2.7 V operation | Preferred for high-voltage industrial systems; unsuitable for ultra-low-power battery designs | Select LM393DR only when operating above 5 V or requiring extended voltage range - not a drop-in replacement for LMV393MM/NOPB in 3.3 V systems |
| TLV3702IDR | Lower supply current (80 µA typ), rail-to-rail input, push-pull output (no external pull-up needed), 350 ns propagation delay | Better for low-noise precision sensing; incompatible with wired-OR bus topologies due to push-pull output | Choose TLV3702IDR when output drive simplicity outweighs need for logic OR functionality - requires PCB redesign for pull-up removal |
Compared with LM393DR and TLV3702IDR, the LMV393MM/NOPB uniquely balances ultra-low quiescent current, guaranteed 2.7 V operation, open-collector flexibility, and industrial temperature support - making it optimal for compact, battery-sensitive dual-threshold detection where wired-OR signaling or level translation is required.

FAQ
What is the maximum supply voltage for LMV393MM/NOPB?
The absolute maximum supply voltage for LMV393MM/NOPB is 5.5 V, but the recommended operating range is 2.7 V to 5 V. Operation above 5 V risks permanent damage per the Absolute Maximum Ratings table. At 5 V, LMV393MM/NOPB delivers optimal propagation delay (200 ns typ) and output saturation (200 mV typ), making it ideal for 5 V logic interfacing while maintaining low power consumption.
Does LMV393MM/NOPB support rail-to-rail input operation?
LMV393MM/NOPB supports input voltages down to −0.1 V (below ground) and up to 4.2 V at 5 V supply - effectively ground-referenced rail-to-rail input capability. This allows direct connection to 0 V-referenced sensors and ADC references without external level-shifting circuitry. However, it does not support true V+–referenced rail-to-rail input like some newer comparators; the upper limit remains ~0.8 V below V+.
Can LMV393MM/NOPB outputs be wired together?
Yes - LMV393MM/NOPB features open-collector outputs that can be safely wired-OR'd using a single external pull-up resistor. This configuration is commonly used in window comparators, fault-bus signaling, and priority interrupt generation. Ensure the pull-up resistor value is between 1 kΩ and 10 kΩ, connected to a voltage within the 2.7–5 V range, and verify total sink current does not exceed 23 mA per output (per datasheet IO specification).
What is the typical input bias current of LMV393MM/NOPB?
The typical input bias current of LMV393MM/NOPB is 25 nA at 5 V and 25°C, with a maximum of 400 nA across the full −40°C to +85°C temperature range. This low bias current minimizes loading errors in high-impedance reference dividers and sensor interfaces - critical for precision threshold detection in battery-operated systems where resistor values >100 kΩ are often used to conserve power.
Is LMV393MM/NOPB RoHS compliant and lead-free?
Yes - LMV393MM/NOPB is RoHS compliant and lead-free, as indicated by the "NOPB" suffix in the part number (No Lead Plating, Pb-Free). It meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements and is qualified for reflow soldering per IPC/JEDEC J-STD-020 standards. The VSSOP-8 package uses matte tin lead finish compatible with standard Pb-free assembly processes.
