Product details
Overview
AZV393MTR-G1 from Diodes Incorporated is a dual general-purpose low-voltage comparator operating from 2.5V to 5.5V supply, featuring 100µA typical supply current, open-collector outputs, and input common-mode range extending to ground-designed for battery-powered portable electronics including notebooks, PDAs, and mobile communications devices.
For engineers reviewing the AZV393MTR-G1 datasheet, AZV393MTR-G1 pinout, AZV393MTR-G1 application, or AZV393MTR-G1 equivalent, key selection criteria include supply current vs. voltage dependency, propagation delay under 100mV overdrive (200–600 ns), output saturation voltage ≤200 mV at 4 mA sink, and compatibility with SOIC-8/TSSOP-8/MSOP-8 footprint constraints.
Technical Context
The AZV393 employs a BiCMOS process with bipolar input and output stages to achieve improved noise immunity and stable operation across industrial temperature (−40°C to +85°C). Its open-collector outputs allow flexible pull-up configuration and wired-OR logic implementation.
Input offset voltage is specified at 1.7–7 mV (typ/max) over full temperature range, and input bias current remains below 250 nA at 25°C. Propagation delay varies with supply voltage and overdrive: at VCC = 5V and 100mV overdrive, TPHL is 200 ns and TPLH is 300 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5V to 5.5V - supports single-cell Li-ion and dual-cell alkaline/battery systems without regulation. |
| Supply Current | 100µA typical at 2.7V - enables multi-year operation in always-on sensor monitoring nodes. |
| Input Offset Voltage | 1.7 mV typical - ensures reliable detection of small differential signals (e.g., thermistor or battery voltage thresholds). |
| Output Saturation Voltage | 200 mV typical at 4 mA sink - minimizes power loss in high-side load switching applications. |
| Propagation Delay | 200 ns (TPHL) at 5V/100mV overdrive - suitable for timing-critical window comparators and oscillator circuits. |
| Input Common-Mode Range | −0.1V to VCC − 0.8V - includes ground reference, enabling direct sensing of 0V-referenced sensors. |
| ESD Rating | 4000 V HBM - provides robust handling during PCB assembly and field deployment. |
Pinout & Package
AZV393MTR-G1 is supplied in green-compliant MSOP-8 package (3.0 mm × 3.0 mm, 0.65 mm pitch), optimized for space-constrained portable designs. Pin assignments are identical 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; sinks up to 84 mA at 5V. |
| 2 | IN 1− | Inverting input - accepts signals down to −0.1V for rail-to-rail threshold detection. |
| 3 | IN 1+ | Non-inverting input - referenced to same common-mode range as IN 1−. |
| 4 | VEE | Ground reference terminal - tied to system GND; enables true ground-sensing capability. |
| 5 | IN 2+ | Non-inverting input for second comparator - independent channel with identical specs. |
| 6 | IN 2− | Inverting input for second comparator - supports dual-threshold or hysteresis configurations. |
| 7 | OUTPUT 2 | Open-collector output - electrically isolated from OUTPUT 1; supports independent load control. |
| 8 | VCC | Positive supply rail - operates from 2.5V to 5.5V; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed 2.5V–5.5V operation | Validated across full industrial temperature range - eliminates need for level-shifting in mixed-supply systems. |
| Low 100µA supply current | Reduces quiescent power by >5× versus legacy LMV393 - critical for coin-cell or energy-harvesting designs. |
| Input common-mode range includes ground | Enables direct interface with 0V-referenced transducers (e.g., current-sense resistors, thermistors). |
| Open-collector outputs | Supports mixed-voltage interfacing (e.g., 3.3V comparator driving 5V logic) and wired-OR bus architectures. |
| BiCMOS process with bipolar I/O | Delivers lower input noise and higher ESD tolerance than CMOS-only comparators. |

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 ICC; wider 2.7V–5.5V supply range; no guaranteed −40°C operation. | Less suitable for extended-temperature portable gear; requires tighter supply regulation below 2.7V. | Select when legacy design reuse or dual sourcing is prioritized over ultra-low ICC. |
| TLV3702IDR | Lower 80µA ICC but rail-to-rail input; 1.8V–5.5V supply; 1.5 mV max VOS; no open-collector output. | Requires level-shifting for 5V logic interfacing; unsuitable for wired-OR or mixed-voltage buses. | Choose when rail-to-rail input swing is mandatory and output flexibility is secondary. |
Compared with LMV393DR2G and TLV3702IDR, AZV393MTR-G1 uniquely balances ultra-low ICC (100µA), ground-sensing inputs, open-collector outputs, and guaranteed −40°C performance - making it optimal for compact, battery-sensitive industrial and consumer portable systems where interface flexibility and temperature resilience are non-negotiable.

FAQ
What is the maximum sink current capability of AZV393MTR-G1 at 3.3V supply?
At VCC = 3.3V and TA = +25°C, the AZV393MTR-G1 delivers 15 mA minimum sink current with VO ≤ 1.5V, per DC electrical characteristics interpolated from 2.7V and 5V test data. This supports direct driving of standard LEDs or logic inputs without external buffers.
Does AZV393MTR-G1 support rail-to-rail input operation?
No - the input common-mode voltage range is specified from −0.1V to (VCC − 0.8V), meaning it does not reach the positive rail. However, it does include ground (VEE), enabling true zero-volt referenced sensing, unlike rail-to-rail input comparators that sacrifice noise immunity.
Can AZV393MTR-G1 be used in a hysteresis configuration?
Yes - its open-collector outputs and stable input bias current (<250 nA) allow precise positive feedback via resistor networks. The 1.7 mV typical input offset voltage ensures predictable hysteresis thresholds without trimming, validated in typical applications circuits for one-shot multivibrators.
Is the MSOP-8 package of AZV393MTR-G1 compatible with standard reflow profiles?
Yes - the AZV393MTR-G1 (G1 suffix) uses a green, lead-free MSOP-8 package qualified for JEDEC J-STD-020C reflow, with peak temperature rating of +260°C for 10 seconds. Its thermal profile matches standard Pb-free assembly processes without derating.
