Low-Power Quad-Channel Digital IsolatorsSilicon

Lab's family of ultra-low-power digital isolators are CMOS devices offering substantialdata rate, propagation delay, power, size, reliability, and external BOM advantagesover legacy isolation technologies.

The operating parameters of these products remainstable across wide temperature ranges and throughout device service life for easeof design and highly uniform performance. All device versions have Schmitt trigger inputsfor high noise immunity and only require VDD bypass capacitors.

Data rates up to 150 Mbps are supported, and all devices achieve propagation delays ofless than 10 ns. Enable inputs provide a single point control for enabling and disablingoutput drive.

Ordering options include a choice of isolation ratings (1.0, 2.5, 3.75 and 5kV) and a selectable fail-safe operating mode to control the default output state duringpower loss.

All products >1 kV are safety certified by UL, CSA, VDE, and CQC, andproducts in wide-body packages support reinforced insulation withstanding up to 5kVRMS.
