Toshiba’s New Device Support Industrial Applications

Toshiba Electronic Devices & Storage Corporation has launched high-speed quad-channel digital isolators, the “DCL54xx01 Series”. Particularly, it features at least 100kV/μsec of high common mode transient immunity (CMTI) and a 150Mbps high-speed data rate. Volume shipments of the six products in the series start today.

Ensuring the safety and reliability of factory automation equipment requires isolation devices that ensure insulation and prevent noise propagation. For that reason, Toshiba offers digital isolators as a solution that address requirements for higher speed and multi-channel signal communications and high CMTI.

Expands Lineup

The new products use Toshiba’s proprietary magnetic coupling type insulated transmission method to deliver a high CMTI of 100kV/μsec (min) [1]. Hence, realizing high tolerance of electrical noise between input/output in isolated signal communications. In addition, it also contributes to stable control signal transmission and equipment operation.

With their low pulse width distortion of 0.8ns (typ.) [2] and high-speed data rate of 150Mbps (max), the digital isolators are suitable for multi-channel high-speed communications applications such as I/O interfaces with SPI communications.

In recent years, Toshiba has provided its customers with photocouplers, isolation devices that ensure insulation through optical coupling, for 50 years now. Going forward, in addition to photocouplers, the company will expand its lineup of high-speed quad-channel digital isolators. Furthermore, the number of channels and packages, and offer high-quality insulation devices that support the reliable, real-time data transmission required for industrial equipment control.
