Digital Isolators, Silicon Laboratories

The Silicon Labs broad range of Digital Isolation products offers significant improvements over older isolation technologies such as opto-couplers. They demonstrate lower power consumption, greater reliability and higher performance, and are generally smaller in size and lower in cost. These CMOS-based devices exhibit stable operating characteristics over a wide temperature range and do not suffer from the lifespan limitations of opto-coupled devices.
