Product details
Overview
MAX22664CAWE/V+ from Analog Devices is a reinforced, six-channel digital isolator in a 16-pin wide SOIC package with 8mm creepage and clearance. It provides bidirectional signal isolation at up to 200Mbps, withstands 5kVRMS for 60s (VISO), supports independent 1.71V–5.5V supplies per side, and delivers 50kV/μs CMTI - enabling robust isolated SPI, CAN, and BMS communication in automotive battery management systems.
For engineers reviewing the MAX22664CAWE/V+ datasheet, MAX22664CAWE/V+ pinout, MAX22664CAWE/V+ application, or MAX22664CAWE/V+ equivalent, key selection criteria include reinforced isolation rating (5kVRMS), AEC-Q100 qualification (/V+ suffix), 200Mbps data rate, low propagation delay (7ns typ at 3.3V), and dual-supply level-shifting capability (1.71V–5.5V on both sides).
Technical Context
The MAX22664CAWE/V+ implements four unidirectional channels from Side A to Side B and two from Side B to Side A - optimized for isolated SPI interfaces where MOSI/MISO/SCLK/CS flow one way and fault/ready signals return. Its proprietary capacitive isolation technology enables reinforced insulation without optocoupler aging or magnetic coupling limitations.
It features integrated undervoltage lockout (1.5V–1.66V threshold) on both VDDA and VDDB, default-high outputs (C variant), and a refresh circuit ensuring output stability during static input conditions - critical for safety-critical automotive applications operating from −40°C to +125°C.

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; 3.75kVRMS isolation; no AEC-Q100 qualification | Suitable for cost-sensitive industrial I/O but not automotive BMS or high-speed SPI | Select when lower speed and non-automotive qualification are acceptable to reduce BOM cost. |
| ISO6760FDWER | 6-channel, 50Mbps, 5000VRMS, but only 25kV/μs CMTI and no AEC-Q100 Grade 0 | Applicable for general-purpose isolation in PLC backplanes, not high-CMTI EV subsystems | Choose for TI ecosystem compatibility and lower power at 50Mbps, but verify CMTI margin in noisy environments. |
Compared with SI8661ED-B-IS and ISO6760FDWER, the MAX22664CAWE/V+ uniquely combines AEC-Q100 Grade 0, 200Mbps speed, 50kV/μs CMTI, and reinforced 5kVRMS isolation - making it the only drop-in option for next-generation automotive BMS and high-fidelity motor control where timing integrity and safety certification are non-negotiable.

FAQ
What is the isolation rating and safety certification status of the MAX22664CAWE/V+?
The MAX22664CAWE/V+ has a reinforced isolation rating of 5000VRMS for 60 seconds (VISO), 848VRMS continuous working voltage (VIOWM), and is UL1577 and cUL certified. It is pending VDE 0884-11 certification for reinforced insulation. The /V+ suffix confirms AEC-Q100 Grade 0 qualification for automotive use from −40°C to +125°C. All certifications apply directly to the MAX22664CAWE/V+ device.
How does the MAX22664CAWE/V+ differ from other members of the MAX22663–MAX22666 family?
The MAX22664CAWE/V+ is the 200Mbps, default-high-output, AEC-Q100 qualified variant with a 4-forward/2-reverse channel configuration. Unlike the 25Mbps B/E versions or unidirectional MAX22666, the MAX22664CAWE/V+ is optimized for isolated SPI. Its "C" suffix denotes high-speed operation, "A" indicates automotive grade, "WE" specifies wide SOIC package, and "/V+" confirms AEC-Q100 qualification - all confirmed in the official Analog Devices ordering guide.
Does the MAX22664CAWE/V+ support level shifting between different logic voltages?
Yes, the MAX22664CAWE/V+ supports true bidirectional level shifting: VDDA can be set from 1.71V to 5.5V independently of VDDB (also 1.71V–5.5V). This allows interfacing a 1.8V microcontroller on Side A with a 5V ADC on Side B, or vice versa - without external level translators. Input thresholds scale with supply voltage (e.g., VIH = 0.7 × VDD_), ensuring reliable logic recognition across the full range.
What is the meaning of the "C" and "/V+" suffixes in MAX22664CAWE/V+?
In MAX22664CAWE/V+, "C" designates the 200Mbps speed grade and default-high output behavior; "A" indicates automotive qualification; "WE" specifies the 16-pin wide SOIC package; and "/V+" explicitly denotes AEC-Q100 Grade 0 qualification with enhanced reliability testing at −40°C and +125°C. These suffixes are defined in Analog Devices' official MAX22663–MAX22666 datasheet Rev 2 (12/2023) and ordering information table.
Can the MAX22664CAWE/V+ be used in medical applications requiring IEC 60601-1 compliance?
The MAX22664CAWE/V+ provides 8mm creepage and clearance plus 5000VRMS reinforced isolation - exceeding basic IEC 60601-1 requirements for patient-connected devices. However, final system-level certification depends on PCB layout, enclosure design, and overall system architecture. The device's VDE 0884-11 pending status and UL/cUL recognition support its use in medically isolated data acquisition paths, but designers must validate the full system per IEC 60601-1 Edition 3.2.
