Skyworks Solutions Inc 4-Channel Digital Isolator 150 Mbps 3.75 kVrms 5.5V 16-Pin SOIC Si8640BC-B-IS1

Skyworks Solutions Inc Si8640BC-B-IS1 is a 4-channel digital isolator designed for high performance and reliable signal isolation in electronic circuits and industrial applications. Operating at a maximum data rate of 150 Mbps, this digital isolator leverages proprietary capacitive isolation technology to deliver low propagation delay, minimal signal skew, and high noise immunity. It supports a maximum isolation voltage of 3.75 kVrms and operates at a supply voltage of 5.5V, making it suitable for demanding environments.

The device comes in a compact 16-pin SOIC package and is intended for surface mount technology (SMT) assembly. With a power dissipation of only 415mW and an input current of 9.2mA, it ensures efficient operation. The Si8640BC-B-IS1 maintains performance across a wide operating temperature range from -40°C to 125°C, fulfilling automotive standard AEC-Q100, as well as IEC, CSA, and UL approvals.

Its compact form factor, measuring 9.9mm in length, 3.9mm in width, and 1.25mm in depth, facilitates integration into space-constrained electronic system designs. The digital isolator is ideal for industrial automation, signal transmission, power electronics, and other applications requiring galvanic isolation with high-speed digital data transfer. Manufactured in Taiwan, Province Of China, it reflects strict quality control and production standards.

This isolator offers four independent digital channels for isolating multiple signals simultaneously. High data rates of up to 150 Mbps allow fast and accurate signal transmission. Low propagation delay of 35 nanoseconds reduces transmission latency.

High isolation voltage rating of 3.75 kVrms protects systems from high voltage differences. Surface mount 16-pin SOIC package simplifies PCB mounting and assembly. Wide operating temperature range and automotive-grade reliability ensure durability in harsh environments.

Meets international safety and quality certifications including IEC, CSA, and UL.
