Product details
Overview
ADUM3210TRZ-EP from Analog Devices is a dual-channel, unidirectional digital isolator using iCoupler® transformer-based isolation technology. It provides 25 Mbps data rate, 25 kV/µs common-mode transient immunity, and operates across −55°C to +125°C with 3.0–5.5 V supply flexibility on both sides. It is used in isolated SPI interfaces and RS-485 transceiver signal conditioning in harsh industrial and aerospace environments.
For engineers reviewing the ADUM3210TRZ-EP datasheet, ADUM3210TRZ-EP pinout, ADUM3210TRZ-EP application, or ADUM3210TRZ-EP equivalent, this page delivers verified electrical specs, military-grade thermal and ESD performance, SOIC_N-8 pin mapping, and validated alternatives for high-reliability system design.
Technical Context
The ADUM3210TRZ-EP implements two independent, input-to-output unidirectional channels (2 inputs on VDD1 side, 0 on VDD2 side), with default-low output logic state. Its monolithic transformer coupling eliminates LED aging and timing drift inherent in optocouplers.
It supports mixed-voltage operation (e.g., 5 V primary / 3.3 V secondary), delivers precise timing (≤3 ns pulse width distortion at 25 Mbps), and meets reinforced insulation requirements per DIN V VDE V 0884-10 (VIORM = 560 V peak) and UL 1577 (2500 V rms).

| Propagation Delay | ≤50 ns at 5 V - Ensures tight timing budgets in real-time control systems with minimal latency. |
| Pulse Width Distortion | ≤3 ns - Preserves signal integrity for clock/data recovery and synchronous protocols. |
| Common-Mode Transient Immunity | ≥25 kV/µs - Maintains reliable operation in noisy motor drives and power converters with fast switching noise. |
| Operating Temperature Range | −55°C to +125°C - Qualified for extended-life deployment in defense, downhole, and avionics applications. |
| Supply Voltage Range | 3.0 V to 5.5 V per side - Supports voltage translation across isolation barrier without level shifters. |
| Isolation Rating | 2500 V rms (UL), 560 V peak VIORM (VDE) - Meets reinforced insulation requirements for functional safety-critical subsystems. |
Pinout & Package
Narrow-body, RoHS-compliant 8-lead SOIC_N (package option R-8, JEDEC MS-012-AA), 5.00 mm × 4.00 mm footprint, 1.27 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD1 | Input-side power supply | 3.0–5.5 V supply for channel inputs VIA/VIB; powers internal encoder circuitry. |
| 2 - VIA | Input A | Digital input signal routed to output VOA; unidirectional path from Side 1 to Side 2. |
| 3 - VIB | Input B | Digital input signal routed to output VOB; second independent unidirectional channel. |
| 4 - GND1 | Input-side ground reference | Return path for VDD1 and input signals; galvanically separated from GND2. |
| 5 - GND2 | Output-side ground reference | Return path for VDD2 and output signals; completes isolated power domain for outputs. |
| 6 - VOB | Output B | Isolated replica of VIB; default-low state ensures fail-safe behavior during power loss. |
| 7 - VOA | Output A | Isolated replica of VIA; matches input logic polarity with <1 µs recovery after VDD restoration. |
| 8 - VDD2 | Output-side power supply | 3.0–5.5 V supply for output drivers VOA/VOB; enables asymmetric voltage operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM3211TRZ-EP | 1 input on VDD1 side, 1 input on VDD2 side (bidirectional configuration); identical package, temp range, and isolation rating. | Supports bidirectional control signaling (e.g., isolated ACK/NACK lines), unlike ADUM3210TRZ-EP's 2-input/0-output-side architecture. | Select ADUM3211TRZ-EP when cross-isolation feedback or handshake signals are required alongside primary data flow. |
| ISO7721DR | Capacitive isolation; 100 Mbps max data rate; 3000 V rms isolation; −40°C to +125°C rating (not −55°C). | Lacks military-grade temperature qualification and AQEC compliance; lower system-level ESD robustness per IEC 61000-4-x. | Choose ISO7721DR only for commercial-temperature, cost-sensitive applications where 100 Mbps speed outweighs extended thermal/safety requirements. |
Compared with ADUM3210TRZ-EP, ADUM3211TRZ-EP offers mirrored I/O directionality for bidirectional protocols, while ISO7721DR trades military qualification and ESD hardening for higher speed and lower unit cost in non-aerospace contexts.

FAQ
What is the default output state of ADUM3210TRZ-EP during power loss?
The ADUM3210TRZ-EP features a default-low output characteristic: when either VDD1 or VDD2 is unpowered, VOA and VOB settle to logic low within 1 µs of supply restoration. This fail-safe behavior prevents unintended activation of downstream circuitry such as gate drivers or transceivers, making ADUM3210TRZ-EP suitable for safety-critical isolation in power electronics and industrial controls.
Does ADUM3210TRZ-EP support mixed-voltage operation between its input and output sides?
Yes, ADUM3210TRZ-EP supports true mixed-voltage operation: VDD1 may be 3.3 V while VDD2 is 5 V (or vice versa), enabling seamless voltage translation across the isolation barrier. Electrical specifications-including propagation delay (≤55 ns), PWD (≤4 ns), and supply current-are fully characterized for these configurations in the official datasheet Rev. A, Tables 7 and 10.
What safety certifications apply to ADUM3210TRZ-EP?
ADUM3210TRZ-EP carries pending approvals for UL 1577 (2500 V rms, 1 min), CSA Component Acceptance Notice #5A, and VDE V 0884-10 (reinforced insulation, VIORM = 560 V peak). Each unit undergoes 100% production testing at ≥1050 V peak per Method B1, with partial discharge <5 pC-fully documented in the Insulation Characteristics section (Page 8) of the datasheet.
How does ADUM3210TRZ-EP differ from standard ADUM3210 variants?
ADUM3210TRZ-EP is the enhanced product (EP) version: it adds military-grade temperature range (−55°C to +125°C), AQEC compliance for defense/aerospace use, controlled manufacturing baseline, and enhanced system-level ESD robustness per IEC 61000-4-x. Standard ADUM3210 parts are rated only from −40°C to +105°C and lack EP-specific qualification data and change notification protocols.
Can ADUM3210TRZ-EP replace ADUM1200-EP in existing designs?
No direct replacement is assured: ADUM3210TRZ-EP improves system-level ESD/burst/surge immunity over ADUM1200-EP via layout and circuit modifications, but pinout differs (ADUM1200-EP uses SOIC-8 wide-body, ADUM3210TRZ-EP uses narrow-body SOIC_N-8), and propagation delay specs vary. Board redesign and layout validation per AN-793 are required before substitution.
