Kawasaki, Japan -- Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched the "DCL54xx01 Series" of high-speed four-channel digital isolators. The series features high common-mode transient immunity (CMTI) of 100kV/μs (min) and a high-speed data rate of 150Mbps. Volume shipments of six products in the series begin today.
To ensure the safety and reliability of factory automation equipment, isolation devices are required to ensure insulation and prevent noise transmission. Toshiba now offers digital isolator solutions to meet market demands for higher speed multi-channel signal communication and high CMTI.
The new product uses Toshiba's proprietary magnetic-coupled isolation transmission method, which provides a high CMTI of 100kV/μs (min) [1]. This not only achieves high tolerance to electrical noise between input/output in isolated signal communication, but also helps ensure stable control signal transmission and device operation. These digital isolators feature low pulse width distortion of 0.8ns (typ) [2] and high-speed data rates of 150Mbps (max), making them suitable for multi-channel high-speed communication applications such as I/O interfaces for SPI communication.
For 50 years, Toshiba has supplied its customers with photocouplers—isolation devices that ensure insulation performance through optical coupling. Going forward, in addition to optocouplers, the company will expand its lineup of high-speed four-channel digital isolators, increase the number of channels and packages, and provide high-quality isolation devices to support the reliable, real-time data transmission.
