MAX14434MAX14436 Four-Channel, Fast, Low-Power, 5kV Digital Isolators RMS General Description Benefits and Features The MAX14434-MAX14436 are fast, low-power, 4-chan- Robust Galvanic Isolation for Fast Digital Signals nel digital galvanic isolators using Maxims proprietary 200Mbps Data Rate process technology. These devices transfer digital sig- Withstands 5kV for 60s (V ) RMS ISO nals between circuits with different power domains while Continuously Withstands 848V (V ) RMS IOWM using as little as 0.58mW per channel at 1Mbps with a Withstands 10kV Surge between GNDA and 1.8V supply. The MAX14434/5/6 have an isolation rating GNDB with 1.2/50s waveform of 5kV for 60 seconds. For applications requiring High CMTI (50kV/s, Typical) RMS 3kV or 3.75kV of isolation, see the MAX14430- RMS RMS Low Power Consumption MAX14432. 1.1mW per Channel at 1Mbps with V = 3.3V DD The MAX14434MAX14436 family offers all three 3.5mW per Channel at 100Mbps with V = 1.8V DD possible unidirectional channel configurations to Options to Support a Broad Range of Applications accommodate any 4-channel design, including SPI, 2 Data Rates (25Mbps, 200Mbps) RS-232, RS-485, and digital I/O applications. Output 3 Channel Direction Configurations enable for the A side of the MAX14435R/S/U/V is active- 2 Output Default States (High/Low) low, making them ideal for isolating a port on a shared SPI bus since the CS signal can directly enable the MISO Applications signal on the isolator. All other devices in the family have Isolated SPI Interface the traditional active-high enable. Fieldbus Communications for Industrial Automation Isolated RS-485/RS-422, CAN Devices are available with a maximum data rate of either Battery Management 25Mbps or 200Mbps and with outputs that are either Medical Systems default-high or default-low. The default is the state the output assumes when the input is either not powered or Safety Regulatory Approvals is open-circuit. See the Ordering Information and Product UL According to UL1577 Selector Guide for suffixes associated with each option. Independent 1.71V to 5.5V supplies on each side of the cUL According to CSA Bulletin 5A isolator also make the devices suitable for use as level translators. The MAX14434MAX14436 are available in a 16-pin wide- body SOIC package with 8mm of creepage and clearance. Ordering Information and Product Selector Guide appear at The package material has a minimum comparative track- end of data sheet. ing index (CTI) of 600V, which gives it a group I rating in creepage tables. All devices are rated for operation at ambient temperatures of -40C to +125C. 19-100102 Rev 6 11/20MAX14434MAX14436 Four-Channel, Fast, Low-Power, 5kV Digital Isolators RMS Absolute Maximum Ratings V to GNDA ........................................................-0.3V to +6V Continuous Power Dissipation (T = +70C) DDA A V to GNDB ........................................................-0.3V to +6V Wide SOIC (derate 14.1mW/C above +70C).......1126.8mW DDB IN , EN on Side A to GNDA ..................................-0.3V to +6V Operating Temperature Range ......................... -40C to +125C IN , EN on Side B to GNDB .................................-0.3V to +6V Maximum Junction Temperature .....................................+150C OUT on Side A to GNDA ......................-0.3V to (V + 0.3V) Storage Temperature Range ............................ -60C to +150C DDA OUT on Side B to GNDB .....................-0.3V to (V + 0.3V) Soldering Temperature (reflow) .......................................+260C DDB Short-Circuit Duration OUT on Side A to GNDA, OUT on Side B to GNDB .....................................Continuous Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device.
