Low-Power Quad-Channel Digital Isolators
KEY FEATURES
Silicon Lab's family of ultra-low-power digital isolators are CMOS devices offering sub-
stantial data rate, propagation delay, power, size, reliability, and external BOM advan- High-speed operation
tages over legacy isolation technologies. The operating parameters of these products DC to 150 Mbps
remain stable across wide temperature ranges and throughout device service life for
No start-up initialization required
ease of design and highly uniform performance. All device versions have Schmitt trigger

Data rates up to 150 Mbps are supported, and all devices achieve propagation delays of
less than 10 ns. Enable inputs provide a single point control for enabling and disabling Reinforced VDE 0884-10, 10 kV surge-

1. Ordering Guide
Industrial and Automotive Grade OPNs
Industrial-grade devices (part numbers having an -I in their suffix) are built using well-controlled, high-quality manufacturing flows to
ensure robustness and reliability. Qualifications are compliant with JEDEC, and defect reduction methodologies are used throughout
definition, design, evaluation, qualification, and mass production steps.
Automotive-grade devices (part numbers having an -A in their suffix) are built using automotive-specific flows at all steps in the manu-
facturing process to ensure robustness and low defectivity. These devices are supported with AIAG-compliant Production Part Approval
Process (PPAP) documentation, and feature International Material Data System (IMDS) and China Automotive Material Data System
(CAMDS) listing. Qualifications are compliant with AEC-Q100, and a zero-defect methodology is maintained throughout definition, de-
sign, evaluation, qualification, and mass production steps.
