Product details
Overview
AZV393MTR-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 serves as a pin-for-pin replacement for LMV393 in battery-powered portable systems requiring low power, small footprint, and rail-to-rail input capability.
For engineers reviewing the AZV393MTR-E1 datasheet, AZV393MTR-E1 pinout, AZV393MTR-E1 application, or AZV393MTR-E1 equivalent, key selection criteria include supply current at 2.7V/5V, output saturation voltage under 1mA sink, input offset voltage ≤7mV, propagation delay <600ns at 100mV overdrive, and compatibility with SOIC-8/TSSOP-8/MSOP-8 PCB footprints.
Technical Context
The AZV393 employs a BiCMOS process with bipolar input and output stages, delivering improved noise immunity versus pure CMOS comparators while maintaining low quiescent current. Its open-collector outputs allow wired-OR logic and flexible pull-up voltage selection independent of VCC.
Designed for operation across -40°C to +85°C, it supports input common-mode voltages down to -0.1V (below ground) and up to 4.2V at 5V supply, enabling direct sensing of signals near system ground or reference rails. Propagation delay varies with input overdrive and load capacitance, with TPHL/TPLH specified at 200–600ns (5V, 100mV overdrive).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5V to 5.5V - Enables direct use with single-cell Li-ion (3.0–4.2V), 3.3V, or 5V logic rails without level shifting. |
| Supply Current (Typ) | 100µA at 2.7V - Reduces battery drain in always-on monitoring circuits; scales linearly with voltage up to 200µA at 5V. |
| Input Offset Voltage (Max) | 7mV at 25°C - Supports accurate threshold detection for signals ≥20mV above noise floor in low-voltage sensor interfaces. |
| Output Saturation Voltage | 200mV at ISINK = 1mA - Ensures reliable logic-low assertion into 3.3V CMOS inputs when pulled up to 3.3V. |
| Propagation Delay | 200ns (TPHL) at 5V, 100mV overdrive - Sufficient for kHz-range window comparators and basic timing circuits like oscillators. |
| Input Common-Mode Range | -0.1V to 4.2V at VCC = 5V - Allows direct comparison of ground-referenced sensors or negative-going transients without biasing resistors. |
| ESD Rating (HBM) | 4000V - Provides robustness against handling damage in manual assembly and field service environments. |
Pinout & Package
Available in lead-free SOIC-8 (M), TSSOP-8 (G), and MSOP-8 (MM) packages. The AZV393MTR-E1 uses the SOIC-8 variant with standard 1.27mm pitch and 5.8mm × 4.0mm body size.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTPUT 1 | Open-collector output of Comparator 1 - Requires external pull-up; sinks current when IN1+ > IN1−. |
| 2 | IN1− | Inverting input of Comparator 1 - Accepts analog signals within −0.1V to VCC−1.2V range. |
| 3 | IN1+ | Non-inverting input of Comparator 1 - Matches IN1− in voltage range and bias current (≤250nA). |
| 4 | VEE | Ground reference terminal - Must be connected to system GND; supports input common-mode down to −0.1V. |
| 5 | IN2+ | Non-inverting input of Comparator 2 - Electrically identical to IN1+; enables dual independent thresholds. |
| 6 | IN2− | Inverting input of Comparator 2 - Paired with IN2+ for second independent comparison path. |
| 7 | OUTPUT 2 | Open-collector output of Comparator 2 - Independent control of second load; shares no internal nodes with OUTPUT 1. |
| 8 | VCC | Positive supply rail - Powers both comparators; rejects supply ripple up to 6V absolute maximum. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed 2.5V–5.5V operation | Validated across full temperature range (−40°C to +85°C), eliminating need for voltage regulators in portable designs. |
| Low 100µA supply current | Enables multi-year battery life in coin-cell–powered wake-up circuits and environmental monitors. |
| Input common-mode range includes ground | Permits direct interface to 0V-referenced sensors (e.g., thermistors, photodiodes) without level-shifting circuitry. |
| Open-collector outputs | Supports mixed-voltage systems: outputs can drive 1.8V, 3.3V, or 5V logic via separate pull-up rails. |
| BiCMOS process architecture | Combines bipolar input stage (low noise, high speed) with CMOS output stage (low power, high gain) for balanced performance. |
Applications
| Notebook and PDA | Low Power, Low Voltage Applications |

Use Scenario: RF power amplifier enable/disable control based on transmit burst detection in Bluetooth modules. IC Role / Device Role / Timing Role: One comparator detects envelope signal; second validates timing window before enabling PA bias. Use Value: 200ns propagation delay ensures sub-microsecond response to RF envelope edges, minimizing transmit latency. |
Use Scenario: Overvoltage/undervoltage lockout in portable test equipment with dual Li-ion packs. IC Role / Device Role / Timing Role: Configured as window comparator to disable main regulator if pack voltage falls outside 6.0–8.4V range.

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 160µA typical ICC at 5V; 9mV max VOS; same SOIC-8 package and pinout. | Suitable where higher speed (150ns TPHL) justifies 60% higher supply current. | Select when propagation delay <200ns is required and battery life is secondary to response time. |
| TLV3702IDR | Lower 80µA ICC but rail-to-rail output (not open-collector); 3.5mV max VOS; requires external pull-down for active-low logic. | Better for driving ADC reference switches or precision references where output voltage swing must reach 0V. | Choose when output must source/sink current bidirectionally and system lacks pull-up infrastructure. |
Compared with LMV393DR2G and TLV3702IDR, the AZV393MTR-E1 delivers optimal balance of ultra-low ICC, open-collector flexibility, and industrial temperature support-making it preferred for cost-sensitive, long-life portable systems where design simplicity and PCB real estate are critical.

FAQ
What is the maximum allowable supply voltage for AZV393MTR-E1?
The absolute maximum VCC rating is 6V per the datasheet's Absolute Maximum Ratings table. Operation above 5.5V violates recommended conditions and risks permanent damage. At 6V, junction temperature rise and leakage currents increase significantly, degrading long-term reliability even if functional temporarily.
Can AZV393MTR-E1 drive a 10kΩ pull-up resistor to 3.3V?
Yes. With ISINK = 330µA (3.3V/10kΩ), the output saturation voltage remains ≤250mV across −40°C to +85°C, ensuring clean logic-low levels for 3.3V CMOS inputs. This is verified in the 5V DC Electrical Characteristics table under VSAT conditions.
Does AZV393MTR-E1 support negative input voltages?
No. The input common-mode range extends only to −0.1V at VCC = 5V (per Recommended Operating Conditions). Applying voltages below −0.1V forward-biases ESD protection diodes, causing excessive input current and potential damage. External clamping is required for true negative signal handling.
Is AZV393MTR-E1 RoHS compliant and halogen-free?
Yes. The "E1" suffix denotes Diodes Incorporated's lead-free, RoHS-compliant construction. Per the Ordering Information section, E1 parts meet JEDEC JS709B and IPC-1752A requirements for halogen-free materials (<900ppm Cl, <900ppm Br, total halogens <1500ppm).
