Skyworks Solutions Inc. SI8421BD-B-IS is a 2-channel, general-purpose digital isolator utilizing capacitive coupling technology. This component offers robust isolation with a working voltage of 5000Vrms and high common-mode transient immunity (CMTI) of 20kV/µs. Designed for reliable data transmission, it supports data rates up to 150Mbps with typical rise and fall times of 2ns. Propagation delay is a maximum of 11ns for both tpLH and tpHL, with a maximum pulse width distortion of 3ns. The device operates within a supply voltage range of 2.7V to 5.5V and across an industrial temperature range of -40°C to 125°C. The SI8421BD-B-IS is packaged in a 16-SOIC (0.295", 7.50mm Width) surface-mount configuration. This isolator is well-suited for applications in industrial automation, power supplies, and medical equipment where signal integrity and protection are critical.
