Detailed Description

The MAX14850 is a six-channel digital isolator. The

seconds. This digital isolator offers a low-power, low-cost,

high electromagnetic interference (EMI) immunity, and sta-

ble temperature performance through Maxim’s proprietary

process technology. The device uses a monolithic solution

to isolate different ground domains and block high-voltage/

high-current transients from sensitive or human interface

circuitry. Four of the six channels are unidirectional, two

in each direction. All four unidirectional channels support

data rates of up to 50Mbps. The other two channels are

bidirectional with data rates up to 2Mbps.

busses can be achieved with the MAX14850. The

independently set the logic levels on either side of the

GNDB, respectively. The MAX14850 features a refresh

mode to ensure accuracy of data when the inputs are DC.

Digital Isolation

The MAX14850 provides galvanic isolation for digital

signals that are transmitted between two ground domains.

well as transient differences of up to 850V.
