SI8660BD-B-IS
Overview
The SI8660BD-B-IS is a high-performance, six-channel digital isolator providing 5000Vrms isolation using Skyworks' proprietary capacitive coupling technology. It supports data rates up to 150Mbps with high common-mode transient immunity (CMTI) of 35kV/us, ensuring reliable data integrity in electrically noisy environments. This unidirectional device is designed to replace optocouplers, offering superior reliability, smaller footprint, and lower power consumption.
Why Choose This Part
This device features industry-leading propagation delay and low skew, which is critical for synchronous multi-channel timing. It operates over a wide supply range of 2.5V to 5.5V and maintains low power consumption, typically 5.0mA on VDD1 and 18.3mA on VDD2 at 50MHz. The 5000Vrms isolation rating and wide SOIC-16 package meet stringent safety requirements for high-voltage barriers.
Applications
Key Specifications
Getting Started
When designing the PCB, place 0.1uF bypass capacitors as close as possible to the VDD1 and VDD2 pins to minimize high-frequency noise. Ensure the isolation gap beneath the SOIC-16 package is kept clear of any copper traces to maintain the 5000Vrms creepage and clearance specifications. For prototyping, look for SOIC-16 wide-body breakout boards or manufacturer-specific evaluation kits that provide pre-populated isolation barriers.
