MAX14434MAX14436 Four-Channel, Fast, Low-Power, 5kV Digital Isolators RMS General Description Benefits and Features The MAX14434MAX14436 are the fastest, lowest power, Robust Galvanic Isolation for Fast Digital Signals 4-channel, digital galvanic isolators on the market today 200Mbps Data Rate using Maxims proprietary process technology. These Withstands 5kV for 60s (V ) RMS ISO Continuously Withstands 848V (V ) devices transfer digital signals between circuits with RMS IOWM different power domains while using as little as 0.58mW per Withstands 10kV Surge between GNDA and GNDB with 1.2/50s waveform channel at 1Mbps with a 1.8V supply. The MAX14434/5/6 have an isolation rating of 5kV for 60 seconds. High CMTI (50kV/s, Typical) RMS The MAX14434MAX14436 family offers all three Low Power Consumption 1.1mW per Channel at 1Mbps with V = 3.3V possible unidirectional channel configurations to DD accommodate any 4-channel design, including SPI, 3.5mW per Channel at 100Mbps with V = 1.8V DD RS-232, RS-485, and digital I/O applications. Output Options to Support a Broad Range of Applications enable for the A side of the MAX14435R/S/U/V is active- 2 Data Rates (25Mbps, 200Mbps) low, making them ideal for isolating a port on a shared 3 Channel Direction Configurations SPI bus since the CS signal can directly enable the MISO 2 Output Default States (High/Low) signal on the isolator. All other devices in the family have Applications the traditional active-high enable. Fieldbus Communications for Industrial Automation Devices are available with a maximum data rate of either Isolated RS-485/RS-422, CAN 25Mbps or 200Mbps and with outputs that are either General Isolation Application default-high or default-low. The default is the state the Battery Management output assumes when the input is either not powered Medical Systems or is open-circuit. See the Ordering Information for suf- fixes associated with each option. Independent 1.71V to Safety Regulatory Approvals (Pending) 5.5V supplies on each side of the isolator also make the UL According to UL1577 devices suitable for use as level translators. cUL According to CSA Bulletin 5A The MAX14434MAX14436 are available in a 16-pin wide- VDE 0884-10 body SOIC package with 8mm of creepage and clearance. The package material has a minimum comparative track- ing index (CTI) of 600V, which gives it a group 1 rating in creepage tables. All devices are rated for operation at ambient temperatures of -40C to +125C.
