Digital isolators are used to provide electrical isolation between two circuits, typically from two separate parts of a system. The SI8661BB-B-IS1 digital isolator is a bidirectional, isolated, serial interface with a maximum data rate of 1 Mbps. It combines a high-speed digital isolation barrier, spread spectrum clock, and a low-power core in a tiny surface-mount package.

The SI8661BB-B-IS1 isolator is designed for use in high-speed, industrial, and consumer applications that require electrical isolation between two circuits or systems of an electronic device. This isolator provides a reliable solution for isolating different components, both within customers’ systems and between systems and the outside environment.

The isolator’s spread spectrum clock enables it to operate with minimal electromagnetic interference. It also supports hot swapping, which means that it can remain powered while an electronic device is being inserted or removed. This helps to minimize disruption and downtime of the system or device. The isolator has a maximum data rate of up to 1 Mbps, allowing it to exchange data quickly between two separate circuits.

The SI8661BB-B-IS1 digital isolator is powered by 2.7 V to 5.5 V and requires no additional external components for operation. Its small 3.9 mm × 4.7 mm surface-mount package provides a space-efficient solution for isolation in any system. It also has a wide operating temperature range of –40°C to 125°C, making it suitable for a range of applications.

The SI8661BB-B-IS1 isolator uses a reliable, self-recoverable MOS technology that ensures a secure data transmission with low distortion, regardless of the distance between the two circuits. It also offers message integrity and data security by providing lossless data transmission with reduced coupling between channels. This isolator is compliant with major safety standards, including IEC 61000-4-2, EN 60601-1, and UL 1577, making it suitable for a wide range of applications.

The SI8661BB-B-IS1 isolator is used in a variety of markets, from industrial control to communications systems. It can provide electrical isolation between two circuits in a data acquisition system, a communication system, or a motor control system. It is also widely used in applications such as PLCs, industrial data networks, medical equipment, and smart home devices. The isolator’s bidirectional nature, high-speed data rate, and wide temperature range, make it a versatile isolator suitable for a range of applications.
