Product details
Overview
MAX22164EAEE+T from Analog Devices is a six-channel, reinforced digital isolator with 4-channel A→B and 2-channel B→A unidirectional signal transfer, 200Mbps maximum data rate, 7ns typical propagation delay at 3.3V, 50kV/μs CMTI, and 3kVRMS isolation rating for automotive and industrial high-noise environments such as battery management systems and isolated SPI interfaces.
For engineers reviewing the MAX22164EAEE+T datasheet, MAX22164EAEE+T pinout, MAX22164EAEE+T application, or MAX22164EAEE+T equivalent, key selection criteria include its 200Mbps high-speed capability, default-low output behavior (E/F variant), dual 1.71V–5.5V supply flexibility, reinforced 3kVRMS isolation, and QSOP-16 package with 4mm creepage for functional safety-critical designs.
Technical Context
The MAX22164EAEE+T implements capacitive galvanic isolation using Analog Devices' proprietary process, supporting independent 1.71V–5.5V supplies on both sides for level translation and noise-immune signal bridging between isolated domains. Its architecture includes a refresh circuit to maintain output accuracy during indefinite DC input states.
It features push-pull output drivers eliminating external pull-ups, undervoltage lockout (1.5V–1.66V threshold) forcing outputs to default-low state during supply faults, and robust ESD protection (±4kV HBM, ±6kV IEC 61000-4-2 contact). All six channels operate independently with guaranteed timing performance across –40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3kVRMS for 60s (UL1577); enables safe operation in high-voltage battery monitoring and motor drive gate driver circuits. |
| Max Data Rate | 200Mbps (C/F variant); supports high-speed isolated SPI, RS-485, and digital I/O in real-time control systems. |
| Propagation Delay | 7ns typ at VDD = 3.3V; ensures low-latency signal transfer critical for closed-loop feedback in inverters and BMS. |
| CMTI | 50kV/μs typ; maintains signal integrity under fast common-mode transients in EV traction inverters and industrial drives. |
| Supply Range | 1.71V–5.5V per side (VDDA/VDDB); allows direct interfacing with 1.8V microcontrollers and 3.3V/5V peripherals without level shifters. |
| Output Default | Default-low (E/F suffix); ensures fail-safe logic state during power-up, brownout, or open-input conditions. |
| Power @ 1Mbps | 0.71mW/channel @ 1.8V; reduces thermal load and enables compact, fanless designs in space-constrained automotive modules. |
Pinout & Package
Package: 16-pin QSOP (E16MS+2), 4mm creepage and clearance, RoHS-compliant, surface-mountable with standard reflow profile (260°C peak).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, VDDA | Side A power supply input | Bypass with 0.1µF capacitor to GNDA; sets logic-high level for IN1–IN6 and determines Side A interface voltage (1.71–5.5V). |
| 2–4, IN1–IN3 | Unidirectional inputs (A→B) | Drive corresponding OUT1–OUT3 on Side B; accept CMOS/TTL logic levels referenced to GNDA. |
| 5–7, IN4–IN6 | Unidirectional inputs (B→A) | Drive corresponding OUT4–OUT6 on Side A; enable bidirectional communication with asymmetric channel allocation. |
| 8, GNDA | Side A ground reference | Return path for VDDA and all Side A signals; must be isolated from GNDB by PCB layout and system grounding. |
| 9, GNDB | Side B ground reference | Return path for VDDB and all Side B signals; forms galvanically isolated domain with GNDA. |
| 10–12, OUT6–OUT4 | Unidirectional outputs (A←B) | Driven by IN4–IN6; provide default-low logic outputs when inputs are unpowered or floating. |
| 13–15, OUT3–OUT1 | Unidirectional outputs (A→B) | Driven by IN1–IN3; push-pull structure eliminates need for external pull-up resistors. |
| 16, VDDB | Side B power supply input | Bypass with 0.1µF capacitor to GNDB; sets logic-high level for OUT1–OUT6 and determines Side B interface voltage (1.71–5.5V). |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation | 3kVRMS withstand (60s), 445VRMS working voltage (VIOWM), and ±10kV surge immunity meet IEC 60747-5-5 and UL1577 requirements for functional safety in automotive BMS. |
| High-Speed Performance | 200Mbps data rate with 7ns propagation delay and 11.1ps clock jitter RMS enables precise timing in isolated ADC sampling and high-frequency PWM control loops. |
| Low-Power Operation | 0.71mW/channel at 1Mbps/1.8V reduces total system power by >40% vs. legacy isolators, extending battery life in portable diagnostic tools. |
| Fail-Safe Default-Low Outputs | E/F variant guarantees LOW state during undervoltage, power-up, or open-circuit conditions-critical for preventing unintended actuation in motor control and safety interlocks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar six-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8661ED-B-IS | 25Mbps max data rate (vs. 200Mbps); 3.75kVRMS isolation; 1.8–5.5V supplies; default-high outputs. | Lower speed suits cost-sensitive industrial I/O where timing margins are relaxed; not suitable for high-speed SPI or BMS real-time balancing. | Select SI8661ED-B-IS only if 25Mbps suffices and default-high behavior aligns with system fault strategy. |
| ISO6764FRDWR | 500Mbps max data rate; 5kVRMS isolation; 1.71–5.5V supplies; default-low outputs; SOIC-16 package (larger footprint than QSOP). | Higher speed and isolation support ultra-fast control loops and higher-voltage systems (e.g., grid-tied inverters); larger package may limit board density. | Choose ISO6764FRDWR when >200Mbps bandwidth or >3kVRMS isolation is required, accepting SOIC-16 mechanical trade-off. |
Compared with SI8661ED-B-IS and ISO6764FRDWR, the MAX22164EAEE+T delivers optimal balance of 200Mbps speed, reinforced 3kVRMS isolation, QSOP-16 compactness, and automotive-grade default-low fail-safety-making it ideal for next-generation EV BMS and high-density industrial controllers where timing, size, and safety are co-constrained.

FAQ
What is the maximum data rate supported by the MAX22164EAEE+T?
The MAX22164EAEE+T supports a maximum data rate of 200Mbps, verified across its full operating temperature range (–40°C to +125°C) and supply voltage range (1.71V to 5.5V). This high-speed capability is specific to the C/F variant family and enables use in demanding applications like isolated high-frequency SPI and real-time BMS communication where latency and throughput are critical. The MAX22164EAEE+T achieves this while maintaining low jitter and tight propagation delay matching.
Does the MAX22164EAEE+T have AEC-Q100 qualification?
Yes, the MAX22164EAEE+T carries the /V suffix in its full part number designation (MAX22164EAEE+T/V), confirming AEC-Q100 qualification for automotive applications. It is rated for operation from –40°C to +125°C ambient temperature and has undergone full automotive-grade stress testing including temperature cycling, humidity bias, and ESD. This makes the MAX22164EAEE+T suitable for deployment in battery management systems, inverter controls, and other safety-critical vehicle subsystems.
What does the 'E' and 'A' in MAX22164EAEE+T indicate?
The 'E' in MAX22164EAEE+T denotes the default-low output configuration, meaning all outputs assume a logic-low state during undervoltage, power-up, or open-circuit input conditions. The 'A' specifies the channel configuration: MAX22164A provides four unidirectional channels from Side A to Side B and two from Side B to Side A. Together, 'EA' identifies this exact variant within the MAX22164 family-ensuring correct functional and timing behavior in designs requiring asymmetric bidirectional isolation.
Can the MAX22164EAEE+T be used for level translation between different logic voltages?
Yes, the MAX22164EAEE+T supports true level translation via independent VDDA (1.71V–5.5V) and VDDB (1.71V–5.5V) supplies. For example, VDDA can be set to 1.8V to interface with a low-power MCU, while VDDB is set to 3.3V or 5V to drive industrial sensors or actuators-without external level shifters. This dual-supply architecture is intrinsic to the device's design and is validated across all operating conditions, making the MAX22164EAEE+T a single-component solution for mixed-voltage isolation and translation.
What safety certifications does the MAX22164EAEE+T hold?
The MAX22164EAEE+T is certified to UL1577 (3000VRMS), cUL (CSA Bulletin 5A), and is pending VDE 0884-11 reinforced insulation certification. It meets IEC 60747-5-5 requirements with 3kVRMS withstand voltage, 445VRMS working voltage (VIOWM), and 6.25kVPK surge rating. These certifications validate its suitability for reinforced insulation in functional safety applications-including automotive BMS, industrial motor drives, and medical equipment-where galvanic separation and fault tolerance are mandated.
