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.
