The MAX14130 are 4-channel 1kV_RMS digital isolators in smaller footprint QSOP packages. For applications requiring 5kV_RMS of isolation, see the MAX14934–MAX14936.

Devices are available with data rates from DC up to 1Mbps, 25Mbps, or 150Mbps. 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 Product Selector Guide and Ordering Information for the 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 MAX14130 are available in a 16-pin (6mm x 5mm) QSOP package. All devices are rated for operation at ambient temperatures of -40°C to +125°C.
