Toshiba Unveils Dual-Channel Digital Isolators for Reliable Data Transmission
Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched four dual-channel, high-speed standard digital isolators for industrial equipment. The new “DCL52xx00 Series” products support stable operation with high common mode transient immunity (CMTI) of 100kV/μs (typ.)[1] and high-speed data rate of 150Mbps (max)[2]. Shipments start today.
The channel configuration of “DCL520C00” and “DCL520D00” is two forward channels, while “DCL521C00” and “DCL521D00” have one forward channel and one reverse channel. These new dual-channel products join the previously released quad-channel products in “DCL54xx01 Series” as standard digital isolators for industrial equipment. With the addition of these new products, Toshiba’s overall lineup now covers 14 products, offering a wide selection of channel configurations and helping to improve design flexibility.
The new DCL52xx00 Series products use Toshiba’s proprietary magnetic coupling type isolated transmission method to achieve a high CMTI of 100kV/μs (typ.), the same as DCL54xx01 Series products. This delivers high level resistance to electrical noise between input and output in isolated signal transmission, enables stable control signal transmission, and contributes to stable equipment operation.
In addition, a low pulse width distortion of 0.8ns (typ.)[3] and a high-speed data rate of 150Mbps (max) are also achieved. The new products are suitable for multi-channel high-speed communication applications such as I/O interfaces with UART[4] and I2C [5] communication.
Toshiba has already started mass production of standard digital isolators for industrial equipment and automotive equipment. Going forward, the company will increase the lineup of packages and number of channels in both areas. It will continue to provide high-quality isolation devices and photocouplers that support the reliability and real-time data transmission required by industrial and automotive equipment.
Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has announced the launch of its new DCL52xx00 Series, a lineup of four dual-channel, high-speed standard digital isolators designed to deliver stable and reliable data transmission in industrial systems. These isolators feature a high common mode transient immunity (CMTI) of 100kV/μs (typ.) and a maximum data rate of 150Mbps, ensuring superior performance even in electrically noisy environments. The series includes two models with dual forward channels (“DCL520C00” and “DCL520D00”) and two with one forward and one reverse channel (“DCL521C00” and “DCL521D00”), complementing Toshiba’s existing quad-channel “DCL54xx01 Series.
With this expansion, Toshiba now offers a total of 14 digital isolator products, providing enhanced design flexibility for engineers working on complex industrial systems. Built using Toshiba’s proprietary magnetic coupling isolation technology, the new devices deliver low pulse width distortion (0.8ns typ.) and high-speed, noise-resistant data transfer, making them ideal for multi-channel communication interfaces such as UART and I²C. Toshiba is already mass-producing these digital isolators for both industrial and automotive applications and plans to further expand its lineup with more package options and channel configurations, reinforcing its commitment to high-quality isolation solutions that ensure reliability and real-time data transmission in next-generation equipment.
Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has introduced the DCL52xx00 Series, a new range of dual-channel, high-speed digital isolators engineered to enhance the stability and performance of data transmission in industrial applications. Featuring a high common mode transient immunity (CMTI) of 100kV/μs (typ.) and supporting data rates up to 150Mbps, the isolators ensure reliable operation even in harsh, noise-prone environments.The lineup includes four models—two with dual forward channels and two with one forward and one reverse channel—expanding Toshiba’s standard digital isolator portfolio to 14 products in total, offering greater design versatility for industrial engineers.
