Introduction
The MAX14430–MAX14432 are fast, low power, 4-channel, digital galvanic isolators using 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 MAX14430/1/2 have an isolation rating of 3.75kVRMS for 60 seconds.
The MAX14430–MAX14432 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 MAX14431R/S/U/V is activelow, making them ideal for isolating a port on a shared SPI bus since the 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. Independent 1.71V to 5.5V supplies on each side of the isolator also make the devices suitable for use as level translators.
The MAX14430–MAX14432 are available in a 16-pin narrow-body SOIC package with 4mm of creepage and clearance. The package material has a minimum comparative tracking index (CTI) of 600V, which gives it a group 1 rating in creepage tables. All devices are rated for operation at ambient temperatures of -40°C to +125°C.
