Maxim Integrated's MAX14934/35 is a family of four-channel, 5 kV digital isolators utilizing Maxim’s proprietary process technology. The MAX14934/35 family transfers digital signals between circuits with different power domains at ambient temperatures up to +125°C.
The MAX14934/35 family offers all three possible unidirectional channel configurations to accommodate any four-channel design including SPI, RS-232, RS-485, and large digital IO modules.
Devices are available with data rates from DC up to 1 Mbps, 25 Mbps, or 150 Mbps. Each device is also available in either a default high or default low configuration. The default is the state an output goes to when its input is unpowered. See the Ordering Information/Selector Guide in the data sheet for the suffixes associated with each option.
Independent 1.71 V to 5.5 V supplies on each side of the isolator also make the devices suitable for use as level translators.
The MAX14934/35 are available in a 16-pin wide body (10.3 mm x 7.5 mm) SOIC package. All devices are rated for operation at ambient temperatures of -40°C to +125°C.
