Communications systems Safety Regulatory Approvals UL 1577 recognized VDE certification conformity Up to 2500 V for 1 minute IEC 60747-5-2 RMS (VDE0884 Part 2) CSA component notice 5A approval IEC 60950-1, 61010-1 (reinforced insulation) Description Skyworks Solutions 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, and 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. All products are safety certified by UL, CSA, and VDE and support withstand voltages of up to 2.5 kV . These devices are available in 16-pin wide- and RMS narrow-body SOIC packages.
