Toshiba launches new digital isolator to help industrial applications achieve stable, high-speed isolated data transmission

—High common-mode transient immunity (CMTI) and high-speed data rates—

Shanghai, China, May 9, 2023 - Toshiba Electronic Components and Storage Corporation ("Toshiba") announced the launch of the new high-speed four-channel digital isolator "DCL54xx01" series, which features a high voltage of 100kV/μs (minimum) Common-mode transient immunity (CMTI) and high-speed data rate of 150Mbps . The six products in this series begin to support mass shipments today.

To ensure the safety and reliability of factory automation equipment, isolation devices are needed to ensure insulation and prevent the spread of noise. Toshiba provides digital isolator solutions to meet the requirements of industrial applications for higher speed, multi-channel signal communication, and high CMTI.

The new product uses Toshiba's proprietary magnetically coupled insulated transmission method to provide a high CMTI of 100kV/μs (minimum)[1]. This not only achieves high tolerance for electrical noise between input/output in isolated signal communication, but also contributes to stable control signal transmission and equipment operation. This digital isolator features low pulse width distortion of 0.8ns (typ) [2] and a high-speed data rate of 150Mbps (maximum), making it suitable for multi-channel high-speed communication applications such as I/O interfaces for SPI communications.

For 50 years, Toshiba has been supplying its customers with optocouplers—isolation devices that ensure insulation performance through optical coupling. Looking forward, in addition to optocouplers, Toshiba will expand its high-speed four-channel digital isolator product line, increase the number of channels and packages, and provide high-quality isolation devices to provide reliable, real-time control required for industrial equipment. Data transfer is supported.
