Product details
Overview
MAX22564CAAP+ 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 across 1.71V–5.5V dual supplies, and is used in isolated SPI interfaces for battery management systems and motor drives.
For engineers reviewing the MAX22564CAAP+ datasheet, MAX22564CAAP+ pinout, MAX22564CAAP+ application, or MAX22564CAAP+ equivalent, key selection criteria include reinforced isolation compliance (UL1577, VDE 0884-11 pending), 20-pin SSOP package with 5.5mm creepage, default-high/low output configuration via DEFA/DEFB, and low-power operation at 1.34mW per channel @1Mbps/3.3V.
Technical Context
The MAX22564CAAP+ implements capacitive galvanic isolation using Analog Devices' proprietary process, supporting bidirectional signal flow across six independent unidirectional channels-four A→B and two B→A. Its architecture includes refresh circuitry to maintain output state 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 logic domains. The device achieves 7ns typical propagation delay at 3.3V and 11.1ps RMS clock jitter, meeting timing-critical requirements in high-speed industrial communications and automotive BMS interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SI8642ED-B-IS | 4-channel, 250Mbps, 5kVRMS, SOIC-16; no default-configurable outputs | Lacks bidirectional channel flexibility and DEFA/DEFB control; requires external pull resistors for fail-safe state | Preferred where higher isolation voltage and smaller footprint are prioritized over configurability |
| ADUM6420ARWZ | 4-channel, 25Mbps, integrated isolated DC-DC converter, SOIC-16; lower speed, higher quiescent current | Includes isolated power but sacrifices data rate and channel count; not suitable for 200Mbps SPI | Selected when board space is constrained and isolated supply is needed, accepting bandwidth trade-off |

FAQ
What is the maximum data rate supported by the MAX22564CAAP+?
The MAX22564CAAP+ supports a maximum data rate of 200Mbps, verified per the C-version specification in the datasheet. This applies across the full operating temperature range (-40°C to +125°C) and supply voltage range (1.71V–5.5V per side). At lower speeds such as 1Mbps, the device consumes only 1.34mW per channel when powered at 3.3V, making it suitable for both high-bandwidth and ultra-low-power applications.
Does the MAX22564CAAP+ provide reinforced isolation certification?
Yes, the MAX22564CAAP+ is certified to UL1577 (File E351759) for 3750VRMS reinforced isolation and is pending VDE 0884-11 certification for reinforced insulation. It withstands 3.75kVRMS for 60 seconds and continuously supports 784VRMS working voltage (VIOWM), meeting safety requirements for automotive BMS and industrial motor drives per IEC 61800-5-1.
How does the MAX22564CAAP+ handle default output states during power loss or floating inputs?
The MAX22564CAAP+ uses DEFA and DEFB pins to configure default output states. When DEFA/DEFB are tied high, outputs default to logic high; when tied low, they default to logic low. This behavior activates during input float, power-down, or open-circuit conditions-ensuring predictable, fail-safe operation without external components. The pins must be held at the same logic level on both sides.
Can the MAX22564CAAP+ be used for level translation between different logic voltages?
Yes, the MAX22564CAAP+ supports independent 1.71V–5.5V supplies on Side A (VDDA/GNDA) and Side B (VDDB/GNDB), enabling seamless level translation. For example, it can interface a 1.8V FPGA I/O bank with a 3.3V sensor ADC or a 5V PLC controller-without external level shifters-while maintaining signal integrity and isolation barrier integrity.
What is the creepage and clearance distance of the MAX22564CAAP+ package?
The MAX22564CAAP+ uses a 20-pin SSOP package (A20MS+7) with minimum creepage and clearance distances of 5.5mm, compliant with DIN VDE 0110 Pollution Degree 2 requirements. This spacing supports reinforced isolation at 3.75kVRMS and enables use in high-potential industrial and automotive applications without additional PCB slotting or conformal coating.
