Product details
Overview
MAX22564CAAP/V+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 AEC-Q100 qualified for automotive battery management and inverter control.
For engineers reviewing the MAX22564CAAP/V+T datasheet, MAX22564CAAP/V+T pinout, MAX22564CAAP/V+T application, or MAX22564CAAP/V+T equivalent, key selection criteria include reinforced isolation rating, side-selectable default output state (via DEFA/DEFB), low propagation delay (7ns typ at 3.3V), and SSOP-20 package with 5.5mm creepage for high-voltage system compliance.
Technical Context
The MAX22564CAAP/V+T implements capacitive-based galvanic isolation using Analog Devices' proprietary process, supporting bidirectional signal flow across six independent unidirectional channels (4A→B, 2B→A). Its architecture includes refresh circuitry to maintain output accuracy during static input conditions and internal 5µA pullups on ENA/ENB pins.
It supports independent 1.71V–5.5V supplies on each side (VDDA/GNDA and VDDB/GNDB), enabling level translation between disparate logic domains. Default output state (high/low) is configured synchronously via DEFA and DEFB pins tied to the same rail, ensuring deterministic behavior during power-up or open-circuit inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VISO | 3.75kVRMS for 60s - meets reinforced insulation requirements per IEC 60747-5-5 for safety-critical automotive and industrial systems. |
| VIOWM | 784VRMS continuous - enables long-term operation in high-noise motor drive or BMS environments without degradation. |
| Max Data Rate | 200Mbps - supports high-speed isolated SPI, CAN FD, or sensor interface protocols without timing bottlenecks. |
| CMTI | 50kV/μs (typ) - ensures reliable operation in fast-switching inverters where common-mode transients exceed 10kV/μs. |
| Propagation Delay | 7ns (typ at VDD = 3.3V) - minimizes system latency in real-time control loops such as traction motor PWM synchronization. |
| Supply Range | 1.71V–5.5V per side - allows direct interfacing with 1.8V microcontrollers and 3.3V/5V peripherals without external level shifters. |
| Power @ 1Mbps | 0.71mW/channel at 1.8V - reduces thermal load in compact, sealed automotive ECUs with strict power budgets. |
Pinout & Package
Package: 20-pin SSOP (A20MS+7), 5.5mm creepage and clearance, RoHS-compliant, rated for -40°C to +125°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | OUT1, OUT2 | Side B outputs driven by IN1/IN2 on Side A - used for isolated command signals to gate drivers or ADCs. |
| 3 | ENA | Active-high enable for Side A inputs - controls power-gating of A-side receivers; internal 5µA pullup ensures default-enable if left floating. |
| 4, 5, 6 | IN1, IN2, IN3 | Side A logic inputs - accept 1.71V–5.5V CMOS levels; VIH = 0.7×VDDA ensures compatibility with diverse host controllers. |
| 7, 8 | IN4, IN6 | Side A/B bidirectional-capable inputs - support configurable directionality (A→B or B→A) depending on device variant wiring. |
| 9, 10 | DEFA, GNDA | Default configuration and ground reference for Side A - DEFA sets output default state and input bias (pullup/pulldown) simultaneously. |
| 11, 12 | GNDB, DEFB | Ground reference and default control for Side B - DEFB must match DEFA state to ensure consistent fail-safe behavior across isolation barrier. |
| 13, 14, 15 | OUT6, OUT5, OUT4 | Side B/A outputs corresponding to IN6/IN5/IN4 - provide reverse-direction feedback or status signals across isolation boundary. |
| 16, 17, 18 | OUT3, OUT2, OUT1 | Side B outputs for IN3/IN2/IN1 - deliver primary control signals to isolated power stage or communication transceivers. |
| 19, 20 | ENB, VDDB | Enable and supply for Side B - ENB has internal 5µA pullup; VDDB bypassed with 0.1µF ceramic capacitor for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualification (/V suffix) | Validated for automotive use up to +125°C ambient, including temperature cycling and HTRB testing per Grade 1 requirements. |
| User-selectable default output state | DEFA/DEFB pins configure all outputs to default-high or default-low during power loss or open inputs - eliminates floating states in safety-critical BMS monitoring. |
| Low jitter clock transmission | 11.1ps RMS clock jitter enables precise timing in isolated ADC sampling or synchronized PWM generation without added phase noise. |
| Integrated refresh circuit | Maintains correct output logic state even when input remains static for extended periods - critical for fault-reporting lines in EV battery packs. |
| High ESD robustness | ±8kV IEC 61000-4-2 contact discharge on GNDB–GNDA - protects against assembly-line ESD events and field service handling. |

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 (B version), 5kVRMS isolation, 3.75kVRMS VISO, 20-SSOP package | Lower speed limits use in high-bandwidth SPI or fast PWM; suitable for cost-sensitive industrial I/O where 200Mbps is unnecessary | Select when system bandwidth ≤25Mbps and AEC-Q100 qualification is not required |
| ISO6760QDWR | 100Mbps max data rate, 5000VRMS VISO, 16-SOIC package, no default-state configuration pins | Lacks DEFA/DEFB control - outputs float or default to fixed state only; smaller footprint but lower channel count flexibility | Select when space-constrained layout prioritizes SOIC over SSOP and bidirectional default control is not needed |
Compared with Si8661ED-B-IS and ISO6760QDWR, the MAX22564CAAP/V+T delivers 200Mbps speed, AEC-Q100 qualification, and user-configurable default outputs - making it uniquely suited for next-generation automotive BMS and inverter designs requiring both performance and functional safety.

FAQ
What is the maximum data rate supported by the MAX22564CAAP/V+T?
The MAX22564CAAP/V+T supports a maximum data rate of 200Mbps under conditions of 2.25V ≤ VDD ≤ 5.5V. This is confirmed in the Dynamic Characteristics section for MAX2256_C devices. At lower supply voltages (1.71V–2.25V), the maximum data rate is 150Mbps. The 200Mbps capability enables high-speed isolated SPI, CAN FD, and sensor interface applications without timing constraints.
Does the MAX22564CAAP/V+T require external pull-up or pull-down resistors on DEFA and DEFB pins?
No, the MAX22564CAAP/V+T does not require external resistors on DEFA or DEFB. These pins are designed to be tied directly to VDDA/GNDA or VDDB/GNDB to set default-high or default-low output states. The datasheet specifies that DEFA and DEFB must be tied to the same logic state, and internal circuitry ensures proper biasing - adding external resistors would conflict with this configuration and is not recommended.
What safety certifications does the MAX22564CAAP/V+T hold?
The MAX22564CAAP/V+T is certified to UL 1577 (3750VRMS), cUL CSA Bulletin 5A, and is pending VDE 0884-11 reinforced insulation approval. It meets IEC 60747-5-5 requirements with 3.75kVRMS withstand voltage (60s), 784VRMS working voltage, and 8kV IEC 61000-4-2 contact ESD. The /V suffix confirms full AEC-Q100 Grade 1 qualification for automotive use from -40°C to +125°C.
How does the MAX22564CAAP/V+T handle static input conditions?
The MAX22564CAAP/V+T incorporates an integrated refresh circuit that periodically samples and retransmits the last valid input state, ensuring stable output logic even when inputs remain static indefinitely. This prevents output drift or metastability in applications like fault-reporting lines in battery management systems, where signals may remain asserted for hours or days without change.
Can the MAX22564CAAP/V+T be used for level translation between different logic families?
Yes, the MAX22564CAAP/V+T supports level translation via independent 1.71V–5.5V supplies on each side (VDDA and VDDB). For example, it can translate 1.8V LVCMOS signals from a microcontroller on Side A to 3.3V or 5V logic on Side B, or vice versa. Input thresholds scale with VDD (VIH = 0.7×VDD), and outputs swing rail-to-rail - eliminating need for external level-shifting components in mixed-voltage systems.
