The patent-pending ISOpro isolator family uses a novel RF isolation architecture fabricated in a standard, 100% CMOS device to deliver a highly-integrated one-to-six-channel isolator that is one-third the size of competing optocoupler solutions reducing the bill of material cost by as much as 50 percent. The digital isolator family are CMOS devices that employ an RF coupler to transmit digital information across an isolation barrier. Very high-speed operation at low power levels is achieved. These parts are available in an 8-pin narrow-body and 16-pin narrow and 16-pin wide-body SOIC package. Two speed grade options (1 and 150 Mbps) are available over the full temperature range and worse case propagation delay of less than 10 ns. Isolator products are pin-for-pin compatible with competing solutions.

The Si8450/55 offers five forward channels, the Si8451 offers four forward channels and one reverse channel, and the Si8452 offers three forward channels and two reverse channels.

The Si8440/45 offers four forward channels, the Si8441 offers three forward channels and one reverse channel, and the Si8442 offers two forward channels and two reverse channels.

The Si8430/35 offers three forward channels while the Si8431 offers two forward and one reverse.

The Si8410 offers one forward channel. The Si8420 offers two forward channels while the Si8421 offers one forward and one reverse channel.

The Si840x offers bidirectional I²C/SMBUS/PMBUS compatible solutions. The Si8400, available in NB SOIC-8, has two bidirectional isolated serial data and serial clock channels. The Si8405, available in NB SOIC-16, adds two additional unidirectional isolated channels for system control signals, such as a reset and an interrupt, which are commonly required for complete I²C bus designs.

The Si84xx products are CSA and UL certified. 
The Si84xx products are VDE certified.
