Features, Applications

The MAX12934/MAX12935 are the fastest, lowest power, 2-channel digital galvanic isolators on the market today, using Maxim's proprietary process technology. These devices transfer digital signals between circuits with different power domains while using as little as 0.65mW per channel at 1Mbps with a 1.8V supply. The two channels of the MAX12935 transfer data in opposite directions, making the MAX12935 ideal for isolating the TX and RX lines of a transceiver. The two channels of the MAX12934 transfer data in the same direction. The MAX12934/MAX12935 have an isolation rating of 5kVRMS for 60 seconds. Both devices are available with a maximum data rate of either 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 not powered or if the input is open-circuit. See the Ordering Information for suffixes associated with each option. Independent to 5.5V supplies on each side of the isolator also make the devices suitable for use as level translators. The MAX12934/MAX12935 are available a 16-pin, wide-body SOIC package. 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 to +125C.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
