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 throughout their
service life. For ease of design, only VDD bypass capacitors are
required.
Data rates up to 150 Mbps are supported, and all devices achieve
worst-case propagation delays of less than 10 ns. These devices are
available in a 16-pin QSOP package.
