Silicon Labs Si841x / Si842x 5kV Digital Isolators

New Additions to the Si84xx ISOpro family

Silicon Labs Si841x and Si842x 5kV digital isolators expand the existing ISOpro family to offer up to 5kV isolation rating options. The robust architecture of the Si841x and Si842x 5kV digital isolators allows for design into safety critical systems with up to 3 times the operating life of opto-coupler based solutions. Silicon Labs Si841x and Si842x 5kV digital isolators support data rates from DC up to 150 Mbps to fit a wide variety of applications from signaling to real time data acquisition. These Silicon Labs devices enable operation in environments that demand higher levels of isolation and protection, industrial and medical applications, and allow for universal power system design with support for global voltage levels.

The Complete Family of Si84xx ISOpro Digital Isolators

The Silicon Labs Si84xx ISOpro digital isolator family features the industry's widest channel count with up to 6 channels in a single package, the highest data rate, lowest power, and highest ESD immunity. These new Silicon Labs ISOpro digital isolator devices are I2C compatible with bi-directional isolated channels on both the serial data (SDA) and serial clock (SCL) lines. The Silicon Labs Si84xx ISOpro family features additional unidirectional isolated data channels that further simplify the end-user BOM and reduce cost and complexity in I2C applications. The Si840xI2C-KIT I²C digital isolator evaluation kit provides a convenient engineering break out board for easy evaluation of the Si840x series.
