Product details
Overview
MAX22564CAAP+T from Analog Devices is a reinforced, six-channel digital isolator with 200Mbps maximum data rate, 3.75kVRMS withstand voltage (60s), and 50kV/μs CMTI. It features four unidirectional channels from Side A to B and two from B to A, operates across 1.71V–5.5V dual supplies, and is used in isolated SPI interfaces within battery management systems.
For engineers reviewing the MAX22564CAAP+T datasheet, MAX22564CAAP+T pinout, MAX22564CAAP+T application, or MAX22564CAAP+T equivalent, key selection criteria include reinforced isolation rating, side-selectable default output state (via DEFA/DEFB), low 7ns propagation delay at 3.3V, and SSOP-20 package with 5.5mm creepage for automotive and industrial safety compliance.
Technical Context
The MAX22564CAAP+T implements capacitive-based galvanic isolation using Analog Devices' proprietary process, enabling reinforced insulation per VDE 0884-11 (pending) and UL1577 certification. Its architecture supports independent 1.71V–5.5V supplies on both sides, allowing bidirectional level translation without external circuitry.
It integrates refresh circuitry to maintain output state during indefinite input static conditions and uses active-high ENA/ENB enables with internal 5µA pullups. The device distinguishes itself within the MAX22563–MAX22566 family by its 4:2 channel directionality-optimized for master-side SPI isolation where MOSI/MISO/SCLK/CS drive from A→B, while interrupt/status signals return B→A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Rating | 3.75kVRMS for 60s - meets reinforced insulation requirements for functional safety in EV BMS and industrial PLCs |
| Max Data Rate | 200Mbps - supports high-speed isolated SPI clocking up to 100MHz with clean eye diagrams |
| Propagation Delay | 7ns (typ) at VDD = 3.3V - enables sub-14ns round-trip latency in closed-loop motor control feedback paths |
| CMTI | 50kV/μs (typ) - ensures robust operation in noisy inverter gate-drive environments with fast dv/dt transients |
| Supply Range | 1.71V–5.5V per side - allows direct interfacing with 1.8V microcontrollers and 3.3V/5V peripherals without level shifters |
| Power @ 1Mbps | 0.71mW/channel @ 1.8V - reduces thermal load in compact, sealed automotive modules |
| Default Output Control | DEFA/DEFB pins set side-wide default-high or default-low - prevents floating states during power sequencing or fault conditions |
Pinout & Package
Package: 20-pin SSOP (A20MS+7), 5.5mm creepage/clearance, RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | OUT1, OUT2 | Side B outputs driven by IN1/IN2 on Side A - used for isolated MOSI and SCLK in SPI |
| 3 | ENA | Active-high enable for Side A inputs - internal 5µA pullup ensures default-enable unless actively disabled |
| 4, 5, 6 | IN1, IN2, IN3 | Side A logic inputs - map to OUT1/OUT2/OUT3 on Side B; IN1–IN3 are A→B only |
| 7, 8 | IN4, IN6 | Side A/B bidirectional inputs - function as IN4/IN6 on Side A and OUT4/OUT6 on Side B (or vice versa) |
| 9, 10 | DEFA, GNDA | Default control 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 - ties output default state across isolation barrier |
| 13, 14, 15 | OUT6, OUT5, OUT4 | Side B outputs driven by IN6/IN5/IN4 on Side A - support B→A status/interrupt signals in SPI slave mode |
| 16, 17, 18 | OUT3, OUT2, OUT1 | Side B outputs - OUT3 is A→B only; OUT2/OUT1 correspond to IN2/IN1 |
| 19, 20 | ENB, VDDB | Enable and supply for Side B - ENB has internal pullup; VDDB requires local 0.1µF ceramic bypass |
Key Features
| Feature | Design Value |
|---|---|
| Reinforced Isolation | 3.75kVRMS withstand (60s) and 784VRMS working voltage - certified to UL1577 and pending VDE 0884-11 for functional safety-critical designs |
| User-Selectable Default State | DEFA/DEFB pins configure all outputs as default-high or default-low - eliminates need for external pull resistors during power-up or fault |
| Low-Power Operation | 0.71mW/channel @ 1Mbps / 1.8V - enables use in thermally constrained automotive junction boxes without forced cooling |
| High-Speed Timing Performance | 7ns typ propagation delay + 11.1ps RMS clock jitter - preserves timing margins in 100MHz SPI and isolated encoder interfaces |
| Wide Supply Flexibility | Independent 1.71V–5.5V VDDA/VDDB rails - supports mixed-voltage systems (e.g., 1.8V MCU + 5V sensor interface) without external translators |
| EMI Robustness | 50kV/μs CMTI and ±12.8kV surge immunity (1.2/50μs) - maintains signal integrity in high-noise motor drives and on-board chargers |
Applications
| Isolated SPI Interface | Battery Management System (BMS) |
|---|---|
Use Scenario: Isolating SPI communication between a main MCU (Side A) and isolated ADCs or cell monitor ICs (Side B) in high-voltage battery packs. IC Role / Device Role: Digital isolator providing galvanic separation between low-voltage control domain and 400–800V battery stack domain.

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; SOIC-20 package with 8mm creepage | Lower speed limits use in high-bandwidth SPI or encoder interfaces; higher creepage suits Class I equipment | Select when cost sensitivity outweighs speed needs and larger creepage is required for regulatory compliance |
| ISO6760FRDWR | 100Mbps max data rate; 5000VRMS isolation; 16-pin SOIC with integrated LDO on Side B | LDO simplifies B-side power but adds quiescent current; lower speed restricts high-frequency serial protocols | Choose when isolated B-side power delivery is preferred over external regulators and 100Mbps suffices for system timing |
Compared with SI8661ED-B-IS and ISO6760FRDWR, the MAX22564CAAP+T delivers 2× higher data rate than the former and 2× higher than the latter, while maintaining identical 20-pin SSOP footprint and supporting user-configurable default states - making it optimal for next-generation automotive and industrial systems requiring both speed and configurability.

FAQ
What is the maximum data rate supported by the MAX22564CAAP+T?
The MAX22564CAAP+T supports a maximum data rate of 200Mbps, verified per the manufacturer's dynamic characteristics table for the 'C' version. This enables high-speed isolated SPI, encoder, and digital I/O applications where timing margins are critical. The 200Mbps capability is maintained across the full 1.71V–5.5V supply range on both sides, with typical performance measured at 3.3V.
Does the MAX22564CAAP+T require external pull-up or pull-down resistors on its input pins?
No, the MAX22564CAAP+T does not require external pull-up or pull-down resistors on its IN_, EN_, or DEF_ pins. Input pins feature programmable internal bias: DEFA/DEFB control whether side-wide pullup (−5µA) or pulldown (+5µA) currents are enabled. This eliminates board space and BOM cost while ensuring deterministic startup and fault-state behavior without external components.
How does the MAX22564CAAP+T differ from the MAX22564BAAP+T?
The MAX22564CAAP+T is the 200Mbps version of the device, whereas the MAX22564BAAP+T is rated for 25Mbps. Both share identical pinout, package, isolation rating (3.75kVRMS), and 4:2 channel directionality. The 'C' variant achieves higher speed through optimized internal circuitry and tighter timing specifications - including 7ns propagation delay vs. 22.6ns typ for the 'B' version - making it suitable for time-critical applications like high-frequency SPI and real-time control loops.
What safety certifications apply to the MAX22564CAAP+T?
The MAX22564CAAP+T is certified to UL1577 (3750VRMS) and cUL (CSA Bulletin 5A), with VDE 0884-11 reinforced insulation certification pending. It meets IEC 60747-5-5 requirements for reinforced isolation, including 3.75kVRMS withstand voltage (60s), 784VRMS working voltage (VIOWM), and 8kVP surge rating. These approvals validate its use in safety-critical automotive and industrial systems requiring dual-insulation redundancy.
Can the MAX22564CAAP+T be used for level translation between different logic families?
Yes, the MAX22564CAAP+T supports true bidirectional level translation: VDDA (1.71V–5.5V) sets Side A logic thresholds, and VDDB (1.71V–5.5V) sets Side B thresholds - independently. This allows interfacing a 1.8V FPGA (Side A) with a 5V sensor interface (Side B) or a 3.3V MCU with 24V industrial I/O, all while maintaining galvanic isolation. No external level-shifting circuitry is needed.
