Product details
Overview
MAX22564CAAP/V+ from Analog Devices is a reinforced, six-channel digital isolator with 200Mbps maximum data rate, 3.75kVRMS isolation rating, and 50kV/μs CMTI. It features four unidirectional channels from Side A to B and two from B to A, operates from 1.71V–5.5V supplies on both sides, and is AEC-Q100 qualified for automotive use in battery management systems and inverters.
For engineers reviewing the MAX22564CAAP/V+ datasheet, MAX22564CAAP/V+ pinout, MAX22564CAAP/V+ application, or MAX22564CAAP/V+ equivalent, key selection criteria include reinforced isolation voltage (3.75kVRMS), side-selectable default output state (via DEFA/DEFB), low propagation delay (7ns typ at 3.3V), and 20-SSOP package with 5.5mm creepage.
Technical Context
The MAX22564CAAP/V+ implements capacitive-based galvanic isolation with proprietary process technology, enabling reinforced insulation certified to UL1577 and pending VDE 0884-11. Its dual-supply architecture (VDDA/GNDA and VDDB/GNDB) supports independent logic-level translation across isolated domains.
It integrates refresh circuitry to maintain output accuracy during indefinite DC input states and features active-high enable inputs (ENA/ENB) with internal 5µA pullups. Channel directionality is fixed per device variant: MAX22564 provides four A→B and two B→A unidirectional paths, confirmed in functional diagrams and pin descriptions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3.75kVRMS for 60s - meets reinforced insulation requirements for safety-critical automotive and industrial systems |
| Max Data Rate | 200Mbps - supports high-speed isolated SPI, RS-485, and digital I/O without timing bottlenecks |
| CMTI | 50kV/μs (typ) - ensures robust operation in noisy motor drive and inverter environments |
| Propagation Delay | 7ns (typ at VDD = 3.3V) - enables sub-10ns latency for real-time control loop isolation |
| Supply Range | 1.71V–5.5V per side - allows direct interfacing with 1.8V, 3.3V, and 5V logic without level shifters |
| Default Output Control | DEFA/DEFB pins set side-wide default-high or default-low state - eliminates floating outputs during power-up or fault conditions |
| Surge Withstand | ±12.8kV (1.2/50μs) between GNDA/GNDB - exceeds IEC 61000-4-5 Level 4 for system-level surge immunity |
Pinout & Package
Package: 20-pin SSOP (A20MS+7), 5.5mm creepage and clearance, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | OUT1, OUT2 | A→B unidirectional outputs - drive downstream logic on Side B with rail-to-rail swing |
| 3 | ENA | Active-high enable for Side A inputs - disables all A-side inputs when low; internal 5µA pullup to VDDA |
| 4, 5, 6 | IN1, IN2, IN3 | A→B unidirectional inputs - accept 1.71V–5.5V logic; VIH = 0.7×VDD_, VIL = 0.8V max |
| 7, 8 | IN4, IN6 | B→A unidirectional inputs - receive signals from Side B; share same electrical specs as IN1–IN3 |
| 9, 10 | DEFA, GNDA | Default configuration and ground reference for Side A - DEFA must match DEFB polarity to avoid undefined behavior |
| 11, 12 | GNDB, DEFB | Ground reference and default control for Side B - DEFB sets B-side output default state and input bias |
| 13, 14, 15 | OUT6, OUT5, OUT4 | B→A unidirectional outputs - drive Side A logic; VOL ≤ 0.4V at 4mA sink, VOH ≥ VDD_ − 0.4V at 4mA source |
| 16, 17, 18 | OUT3, IN5, ENB | A→B output, B→A input, and B-side enable - IN5 is B→A; ENB has internal 5µA pullup to VDDB |
| 19, 20 | VDDA, VDDB | Independent power supplies for each side - bypass each with 0.1µF ceramic capacitor near pin |
Key Features

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; 5kVRMS isolation; 16-pin SOIC package | Limited to lower-speed interfaces like isolated UART or slow GPIO; not suitable for 200Mbps SPI or fast BMS telemetry | Select when cost sensitivity outweighs speed and automotive qualification requirements |
| ISO6760QDWR | 100Mbps max data rate; 5000VRMS isolation; 16-pin SOIC; no AEC-Q100 qualification | Supports higher isolation voltage but lacks automotive temperature range and default-output control pins | Prefer for industrial AC/DC power supplies where extended temperature range is not required |
Compared with SI8661ED-B-IS and ISO6760QDWR, the MAX22564CAAP/V+ delivers 2× higher data rate than the former and 2× faster timing than the latter, while uniquely combining AEC-Q100 qualification, side-selectable defaults, and 200Mbps capability in a 20-SSOP package.

FAQ
What is the maximum data rate supported by the MAX22564CAAP/V+?
The MAX22564CAAP/V+ supports a maximum data rate of 200Mbps, verified under 2.25V–5.5V supply conditions. This performance is specified in the Dynamic Characteristics section for MAX2256_C devices and applies directly to the MAX22564CAAP/V+ variant. The 200Mbps capability enables high-fidelity isolated communication in applications such as fast SPI buses and real-time BMS telemetry links.
Does the MAX22564CAAP/V+ have AEC-Q100 qualification?
Yes, the MAX22564CAAP/V+ is AEC-Q100 qualified (Grade 0, -40°C to +125°C), as indicated by the "/V" suffix in its part number and confirmed in the Product Highlights and Detailed Description sections. This qualification covers temperature cycling, humidity testing, and ESD robustness, making it suitable for under-hood automotive applications including hybrid electric vehicle inverters and battery management systems.
How does the default output configuration work on the MAX22564CAAP/V+?
The MAX22564CAAP/V+ uses DEFA and DEFB pins to configure default output states: tying DEFA to VDDA sets all Side A outputs default-high and enables input pullups; tying it to GNDA sets them default-low and enables pulldowns. DEFB operates identically on Side B. Both pins must be tied to the same logic state (high or low) to ensure deterministic behavior, as explicitly required in the Pin Descriptions table.
What isolation certifications does the MAX22564CAAP/V+ hold?
The MAX22564CAAP/V+ is certified to UL1577 (3750VRMS) and cUL CSA Bulletin 5A, with pending VDE 0884-11 (Reinforced Insulation) approval. Its insulation characteristics include VIOWM = 784VRMS continuous, VISO = 3750VRMS for 60s, and VIOSM = 8000VPEAK surge rating - all documented in Table 1 and Safety Regulatory Approvals sections of the datasheet.
Can the MAX22564CAAP/V+ be used for level translation between different logic voltages?
Yes, the MAX22564CAAP/V+ supports independent 1.71V–5.5V supplies on Side A (VDDA/GNDA) and Side B (VDDB/GNDB), enabling bidirectional level translation. For example, it can interface a 1.8V FPGA on Side A with a 3.3V microcontroller on Side B while maintaining signal integrity and isolation - a capability confirmed in the Level Shifting section and DC Electrical Characteristics tables.
