SKYWORKS SI8661BC B IS1 ultra digital isolator with minimal propagation delay and high noise immunity
Product Overview
Skyworks' Si8660/61/62/63 series are ultra-low-power, six-channel digital isolators designed for high-speed data transfer with minimal power consumption. These CMOS devices offer significant advantages over traditional isolation technologies, including improved data rates, reduced propagation delay, lower power usage, smaller size, enhanced reliability, and a simplified external Bill of Materials (BOM). They maintain stable operating parameters across wide temperature ranges and throughout their service life, ensuring consistent performance. Key features include Schmitt trigger inputs for superior noise immunity, support for data rates up to 150 Mbps, and propagation delays under 10 ns. Options for isolation ratings (1.0, 2.5, 3.75, and 5 kV) and selectable fail-safe modes are available. These devices are safety certified by UL, CSA, VDE, and CQC, with wide-body packages supporting reinforced insulation up to 5 kVRMS. Automotive Grade versions are available, built with automotive-specific manufacturing processes for enhanced robustness and low defectivity.
