Product details
Overview
MAX22441CAEE+T from Analog Devices is a reinforced, ultra-low-power, 4-channel digital isolator in 16-pin QSOP package with 3000VRMS isolation rating (60s), ±10kV surge capability, 200kV/µs CMTI, and 10Mbps max data rate. It features asymmetric channel directionality (3 channels A→B, 1 channel B→A), operates from 1.71V to 5.5V per side, and targets battery-powered industrial I/O and loop-powered sensor interfaces.
For engineers reviewing the MAX22441CAEE+T datasheet, MAX22441CAEE+T pinout, MAX22441CAEE+T application, or MAX22441CAEE+T equivalent, key selection criteria include its 9.6µA/channel DC supply current at 3.3V, 43.8ns typical propagation delay, reinforced insulation certification status, and QSOP footprint compatibility with space-constrained PLC and BMS designs.
Technical Context
The MAX22441CAEE+T implements galvanic signal isolation across an internal dielectric barrier using Analog Devices' proprietary process technology. Its channel architecture supports mixed-direction data flow: three unidirectional A→B channels and one reverse-direction B→A channel, enabling bidirectional communication without external logic inversion.
It integrates independent undervoltage lockout (UVLO) on both sides (1.6V threshold), active-high enable controls (ENA/ENB), and operates over –40°C to +125°C ambient. The device meets reinforced insulation requirements per VDE 0884-11 (pending) and delivers 445VRMS continuous working voltage with 1.5pF barrier capacitance for low noise coupling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISO6741QDWR | 4-channel, 5000VRMS wide-SOIC package, 10Mbps, but higher 22µA/channel DC current at 3.3V | Higher isolation rating suits mains-connected equipment; wider SOIC requires more PCB area | Select when 5000VRMS certification is mandatory and board space permits larger footprint |
| ADUM2401ARWZ | 4-channel, 5000VRMS, 1Mbps max data rate, 1.71–5.5V supply, but no mixed-direction channel option | Limited to unidirectional-only configurations; requires external logic for bidirectional protocols | Choose for cost-sensitive, lower-speed applications where full-duplex isolation is not required |
Compared with ISO6741QDWR and ADUM2401ARWZ, the MAX22441CAEE+T uniquely combines QSOP compactness, 10Mbps speed, ultra-low 9.6µA/channel DC consumption, and native mixed-direction channel architecture-making it optimal for space-constrained, battery-aware, and full-duplex isolated interfaces.

FAQ
What is the maximum data rate supported by the MAX22441CAEE+T?
The MAX22441CAEE+T supports a maximum data rate of 10Mbps, verified across its full operating temperature range (–40°C to +125°C) and supply voltage range (1.71V to 5.5V per side). This enables reliable isolation of high-speed SPI, RS-485 transceiver control lines, and digital I/O in real-time industrial networks. The device maintains timing integrity with 43.8ns typical propagation delay and <10ns channel-to-channel skew.
Does the MAX22441CAEE+T support bidirectional communication natively?
Yes, the MAX22441CAEE+T supports native bidirectional communication via its asymmetric channel configuration: three channels transmit A→B (IN1–IN3 → OUT1–OUT3), while one channel transmits B→A (IN4 → OUT4). This eliminates external inverters or additional isolators needed for full-duplex protocols like isolated UART or SPI with command/response handshaking.
What safety certifications does the MAX22441CAEE+T currently hold?
The MAX22441CAEE+T is pending UL1577, VDE 0884-11 (reinforced insulation), CSA IEC 62368-1, and IEC 61010-1 certifications. As a 16-QSOP device, it is rated for 3000VRMS isolation (60s), 445VRMS continuous working voltage, and ±10kV surge immunity - meeting baseline reinforced insulation requirements for industrial end-equipment before final certification issuance.
How does the power consumption of the MAX22441CAEE+T compare at different data rates?
At 3.3V supply, the MAX22441CAEE+T draws 9.6µA per channel at DC, 13.2µA at 100kbps, and 47.6µA at 1Mbps. This ultra-low quiescent current enables multi-year operation in energy-harvesting and loop-powered systems. The increase with data rate reflects dynamic switching losses, not leakage - ensuring predictable battery life modeling across operating conditions.
Can the MAX22441CAEE+T operate with different supply voltages on each side?
Yes, the MAX22441CAEE+T supports independent 1.71V to 5.5V supplies on Side A (VDDA/GNDA) and Side B (VDDB/GNDB), enabling seamless level translation between 1.8V microcontrollers and 3.3V or 5V peripherals. This eliminates external level shifters in mixed-voltage systems such as isolated ADC interfaces or sensor hubs with heterogeneous logic families.
