Product details
Overview
MAX22164CAEE+ from Analog Devices is a six-channel, reinforced digital isolator in 16-QSOP package with 4mm creepage/clearance, rated for 3kVRMS withstand voltage (60s), 445VRMS working voltage, and 200Mbps max data rate. It features four unidirectional channels from Side A to B and two from B to A, operates from 1.71V–5.5V supplies per side, and delivers 7ns typical propagation delay at 3.3V - ideal for isolated SPI interfaces in automotive BMS and industrial inverters.
For engineers reviewing the MAX22164CAEE+ datasheet, MAX22164CAEE+ pinout, MAX22164CAEE+ application, or MAX22164CAEE+ equivalent, this page provides verified channel directionality (4A→B / 2B→A), CMTI of 50kV/μs, low-power operation (1.34mW/channel @1Mbps/3.3V), safety certifications (UL1577, cUL, VDE pending), and precise QSOP pin mapping - all confirmed from Analog Devices' official Rev 6 datasheet (11/23).
Technical Context
The MAX22164CAEE+ implements capacitive galvanic isolation using Analog Devices' proprietary process, supporting bidirectional signal flow across six independent unidirectional channels (four A→B, two B→A). Its dual 1.71V–5.5V supplies (VDDA/GNDA and VDDB/GNDB) enable level translation between disparate logic domains while maintaining reinforced insulation integrity.
It features an internal refresh circuit ensuring output stability during indefinite DC input states, undervoltage lockout (1.6V threshold) forcing outputs to default-high state on supply fault, and push-pull outputs eliminating external pull-ups. All channels meet 50kV/μs CMTI and support operation from –40°C to +125°C ambient.

FAQ
What is the channel configuration of the MAX22164CAEE+?
The MAX22164CAEE+ has four unidirectional channels from Side A to Side B (IN1→OUT1, IN2→OUT2, IN3→OUT3, IN4→OUT4) and two unidirectional channels from Side B to Side A (IN5→OUT5, IN6→OUT6). This 4A→B / 2B→A arrangement is optimized for isolated SPI interfaces, where MOSI, SCLK, CS, and address lines flow one way and MISO and status signals return the other. The MAX22164CAEE+ pinout and functional diagram confirm this exact configuration.
Does the MAX22164CAEE+ support AEC-Q100 qualification?
The MAX22164CAEE+ itself is not AEC-Q100 qualified, but it belongs to the MAX22163–MAX22166 family where /V suffix variants (e.g., MAX22164CAEE+V) are explicitly AEC-Q100 qualified for automotive use. The MAX22164CAEE+ shares identical electrical specs, package, and operating temperature range (–40°C to +125°C), making it suitable for pre-qualification prototyping and non-safety-critical automotive subsystems where full qualification is not mandated.
What are the supply voltage requirements for MAX22164CAEE+?
The MAX22164CAEE+ requires two independent supplies: VDDA (1.71V–5.5V relative to GNDA) for Side A inputs and VDDB (1.71V–5.5V relative to GNDB) for Side B outputs. Both supplies must be bypassed with 0.1µF ceramic capacitors. This dual-supply architecture enables level translation - for example, interfacing a 1.8V FPGA (Side A) with a 3.3V ADC (Side B) - while maintaining full isolation integrity and timing performance across the entire voltage range.
How does the MAX22164CAEE+ handle undervoltage conditions?
The MAX22164CAEE+ features independent undervoltage lockout (UVLO) on both VDDA and VDDB, with a 1.6V threshold and 45mV hysteresis. If either supply drops below UVLO, all outputs transition to their default-high state regardless of input logic - preventing undefined behavior during power-up, brownout, or supply sag. This behavior is documented in Table 2 of the datasheet and applies identically to all six channels of the MAX22164CAEE+.
What safety certifications does the MAX22164CAEE+ hold?
The MAX22164CAEE+ is certified to UL1577 (3000VRMS isolation) and cUL (CSA Bulletin 5A), with VDE 0884-11 reinforced insulation certification pending. It meets reinforced insulation requirements per IEC 60747-5-5, including 3kVRMS withstand (60s), 445VRMS working voltage, and ±10kV surge immunity (1.2/50μs). These ratings are validated for the 16-QSOP package with 4mm creepage and clearance, as specified in the MAX22164CAEE+ datasheet.
