Digital Isolators are electronic components which provide electrical isolation between two or more circuits or subsystems. They are commonly used in systems that require electrical isolation for safety and/or system performance such as motor drives, medical equipment, power supplies, and automotive applications. The SI8641ED-B-IS is a digital isolator that provides electrical isolation of digital signals or power between two circuits.

The SI8641ED-B-IS is a low-power, low-latency digital isolator with an 8-bit bidirectional data bus. It provides a datalink of up to 8Kb/s and operates from a single 3.3V supply with no external components needed. The device features fail-safe operation with ESD protection up to ±7kV, as well as a wide common mode range rating of ±7.5kV. This makes it an ideal choice for high-speed communication applications in harsh environments.

The SI8641ED-B-IS is designed to bridge the gap between isolated digital systems and their corresponding power signals. The device features a CMOS dual rail-to-rail input stage for high signal fidelity and an integrated low power CMOS output stage for low energy consumption. The isolator also has an integrated 5-bit addressable register that allows for up to 32 pre-programmed configurations.

The SI8641ED-B-IS isolator utilizes a patented technology called “XTP” (Cross-Time-Domain Isolation) which provides fast, reliable electrical isolation of digital signals. XTP allows for two data transfers, one in the forward direction and one in the reverse direction, to occur simultaneously across one isolated barrier. This technique eliminates the need for additional components, and consequently reduces power consumption and cost. The device also has a low-frequency (3Hz) High-Frequency Error Rejection (HEFR) input filter to ensure smooth signal transfer and reduce EMI/RFI interference.

The SI8641ED-B-IS isolator is a highly reliable component that is ideal for demanding applications that require electrical isolation, high signal fidelity, and a low-cost solution. The device is well-suited for a wide variety of industrial applications including motor drives, power supplies, solar inverters, medical equipment, automotive applications, opto-couplers, HVAC systems, and speech recognition systems. This isolator is also used for secure communications as it ensures data integrity and provides protection from electrical noise.
