The MAX12934-MAX12935 are fast, low-power, 2-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 0.65mW 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 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 not powered or if the input 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 MAX12934/MAX12935 are available in a 16-pin, wide-body SOIC package. 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.ApplicationsBattery ManagementFieldbus Communications for Industrial AutomationGeneral Isolation ApplicationIsolated RS232, RS-485/RS-422, CANMedical Systems
