General Description

Silicon Lab's family of ultra-low-power digital isolators are CMOS devices offering substantial data rate, propagation delay, power, size, reliability, and external BOM advantages when compared to legacy isolation technologies.

The operating parameters of these products remain stable across wide temperature ranges and throughout device service life for ease of design and highly uniform performance.

All device versions have Schmitt trigger inputs for high noise immunity and only require VDD bypass capacitors.
