Categories: Digital Isolators

Quality Control: Learn More

Skyworks Solutions Inc. SI8421-B-IS is a general-purpose, 2-channel digital isolator utilizing capacitive coupling technology. This component offers 2500Vrms of isolation and supports a data rate of up to 10Mbps. It features robust Common Mode Transient Immunity (CMTI) of 25kV/µs, ensuring reliable operation in noisy environments. The device operates with a supply voltage range of 2.375V to 5.5V and has a maximum propagation delay of 35ns for both low-to-high and high-to-low transitions. Pulse width distortion is limited to a maximum of 7.5ns, with typical rise and fall times of 2ns. Packaged in an 8-SOIC (0.154", 3.90mm width) for surface mounting, this unidirectional isolator is suitable for applications in industrial automation, power supplies, and medical equipment. The operating temperature range is -40°C to 125°C.
