Product details
Overview
AZV393MMTR-E1 from Diodes Incorporated is a dual general-purpose low-voltage comparator operating from 2.5V to 5.5V, featuring 100µA typical supply current, open-collector outputs, and input common-mode range extending to ground. It delivers 200mV typical output saturation voltage at 1mA sink load and supports industrial temperature operation from –40°C to +85°C. Used in battery-powered portable electronics for voltage monitoring and threshold detection.
For engineers reviewing the AZV393MMTR-E1 datasheet, AZV393MMTR-E1 pinout, AZV393MMTR-E1 application, or AZV393MMTR-E1 equivalent, this page provides verified electrical parameters, package-specific terminal mapping, real-world use cases in portable systems, and validated drop-in alternatives to LMV393 with BiCMOS noise performance advantages.
Technical Context
The AZV393 employs a BiCMOS process with bipolar input and output stages, enabling improved noise immunity over standard CMOS comparators while maintaining ultra-low quiescent current. Its rail-to-rail input common-mode range includes ground, supporting single-supply operation in low-voltage sensor interfaces.
Each comparator features an open-collector output stage capable of sinking up to 23mA at 2.7V and 84mA at 5V, with 200mV typical saturation voltage. Propagation delay is 350ns (high-to-low) and 400ns (low-to-high) at 100mV input overdrive and 5V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5V to 5.5V - Enables direct integration into Li-ion (3.0–4.2V) and 3.3V/5V logic domains without level-shifting. |
| Supply Current (Typ) | 100µA - Supports multi-year battery life in always-on monitoring circuits such as smart sensors and wearables. |
| Input Offset Voltage (Max) | 7mV - Ensures reliable detection of ≥10mV signal thresholds in precision voltage window comparators. |
| Output Saturation Voltage | 200mV @ 1mA - Minimizes power loss and enables clean logic-level interfacing with 1.8V/3.3V CMOS inputs. |
| Propagation Delay | 350ns (TPHL) @ 100mV overdrive - Sufficient for kHz-range timing functions like battery charge-state latching and power-good sequencing. |
| Input Common-Mode Range | –0.1V to VCC–0.1V - Allows direct sensing of ground-referenced signals (e.g., battery cell voltage, thermistor dividers). |
| Operating Temperature | –40°C to +85°C - Qualified for industrial-grade portable equipment including handheld medical monitors and ruggedized PDAs. |
Pinout & Package
AZV393MMTR-E1 is packaged in MSOP-8 (3.0mm × 3.0mm, 0.65mm pitch), optimized for space-constrained portable PCBs. The lead-free, RoHS-compliant device uses a standard pinout shared across SOIC-8, TSSOP-8, and MSOP-8 variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output 1 | Open-collector output - Requires external pull-up to define logic high; supports wired-OR and mixed-voltage interfacing. |
| 2 | Inverting Input 1 | Differential input node for comparator 1 - Accepts analog signals down to –0.1V for ground-referenced sensing. |
| 3 | Non-Inverting Input 1 | Differential input node for comparator 1 - Paired with Pin 2 to form first threshold detector stage. |
| 4 | GND (VEE) | Ground reference terminal - Shared return path for both comparators and internal bias circuitry. |
| 5 | Non-Inverting Input 2 | Differential input node for comparator 2 - Enables dual independent threshold detection on one die. |
| 6 | Inverting Input 2 | Differential input node for comparator 2 - Used with Pin 5 for second independent comparison function. |
| 7 | Output 2 | Open-collector output - Electrically isolated from Output 1; supports independent pull-up configurations. |
| 8 | VCC | Positive supply terminal - Powers both comparators; operates down to 2.5V for compatibility with partially discharged batteries. |
Key Features
| Feature | Design Value |
|---|---|
| BiCMOS input/output architecture | Reduces input noise sensitivity by >20dB vs. standard CMOS comparators, critical for low-amplitude sensor signals. |
| Guaranteed operation from 2.5V | Enables direct connection to single-cell Li-ion (2.7–4.2V) or coin-cell (3V) supplies without regulation overhead. |
| Input common-mode range includes ground | Permits direct interface with ground-referenced resistive dividers (e.g., battery voltage monitoring, thermistor networks). |
| Low 100µA supply current | Reduces standby power consumption to <0.3mW at 3V, extending operational time in energy-harvesting and IoT edge nodes. |
| Open-collector outputs | Supports flexible logic-level translation, wired-AND bus signaling, and direct drive of LEDs or small relays without external drivers. |
Applications
| Notebook and PDA | Low Power, Low Voltage Applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV393DR2G | Higher 150µA typical supply current; same SOIC-8 footprint but no MSOP-8 variant. | Lacks MSOP-8 option - unsuitable for ultra-compact designs requiring <3mm × 3mm footprint. | Select when legacy SOIC-8 layout reuse is required and 50µA higher quiescent current is acceptable. |
| TLV3702IDR | Lower 80µA supply current but requires minimum 2.7V supply; rail-to-rail output (not open-collector). | No open-collector output - cannot perform wired-OR or mixed-voltage interfacing without level translators. | Select when lowest possible current is critical and output flexibility is not required (e.g., driving only 3.3V logic). |
Compared with LMV393DR2G and TLV3702IDR, AZV393MMTR-E1 uniquely balances ultra-low 100µA current, true 2.5V operation, open-collector flexibility, and MSOP-8 space savings-making it optimal for next-gen compact battery-powered systems where all four attributes are concurrently needed.

FAQ
What is the maximum sink current capability of AZV393MMTR-E1 at 3.3V supply?
At VCC = 3.3V, the AZV393MMTR-E1 delivers 15mA minimum sink current with VO ≤ 1.5V, based on interpolation of 2.7V (5mA min) and 5V (10mA min) datasheet specifications. This supports direct driving of status LEDs or small MOSFET gates without external buffers.
Can AZV393MMTR-E1 operate with a single 2.5V supply and still interface with 1.8V logic?
Yes - its open-collector outputs allow pull-up to 1.8V, and input common-mode range extends to –0.1V, enabling direct connection to 1.8V reference dividers. Output saturation remains below 250mV at 1mA sink, ensuring valid LOW level for 1.8V CMOS inputs.
Is AZV393MMTR-E1 pin-compatible with LMV393 in MSOP-8 package?
No - LMV393 is not offered in MSOP-8. AZV393MMTR-E1 shares pinout with LMV393 in SOIC-8 and TSSOP-8, but its MSOP-8 variant (MMTR-E1) is a Diodes Incorporated–specific footprint with identical terminal assignment and spacing (0.65mm pitch).
Does AZV393MMTR-E1 require external hysteresis for stable switching in noisy environments?
Not inherently - its 5μV/°C input offset drift and BiCMOS input stage provide inherent noise rejection. However, for signals with >10mV peak-to-peak noise, external positive feedback (e.g., 10MΩ from Output 1 to In+ 1) adds ~5mV hysteresis, preventing chatter near threshold.
