MAX14436FAWE+ by Analog Devices

Four-Channel, Fast, Low-Power, 5kVRMS Digital Isolators


The MAX14434-MAX14436 are fast, low-power, 4-channel digital galvanic isolators using Maxim’s proprietary process technology.These devices transfer digital signals between circuits with different power domains while using as little as 0.58mW per channel at 1Mbps with a 1.8V supply. The MAX14434/5/6 have an isolation rating of 5kVRMS for 60 seconds. For applications requiring 3kVRMS or 3.75kVRMS of isolation, see the MAX14430-MAX14432. The MAX14434–MAX14436 family offers all three possible unidirectional channel configurations to accommodate any 4-channel design, including SPI, RS-232, RS-485, and digital I/O applications. Output enable for the A side of the MAX14435R/S/U/V is active-low, making them ideal for isolating a port on a shared SPI bus since the active-low CS signal can directly enable the MISO signal on the isolator. All other devices in the family have the traditional active-high enable. Devices are available with a maximum data rate of either 25Mbps or 200Mbps and with outputs that are either default-high or default-low. The default is the state the output assumes when the input is either not powered or is open-circuit. See the Ordering Information and Product Selector Guide for suffixes associated with each option. Independent 1.71V to 5.5V supplies on each side of the isolator also make the devices suitable for use as level translators. The MAX14434–MAX14436 are available in a 16-pin wide-body SOIC package with 8mm of creepage and clearance. The package material has a minimum comparative tracking index (CTI) of 600V, which gives it a group I rating in creepage tables. All devices are rated for operation at ambient temperatures of -40°C to +125°C.
