Toshiba DCM34xx01 Series digital isolators

Toshiba Electronic Devices & Storage Corporation has launched a line-up of 4-channel high-speed standard digital isolators for automotive applications. The DCM34xx01 Series features 10 devices that support stable operation with high common-mode transient immunity (CMTI) of 100 kV/μs (typ.) and a high data transmission rate of 50 Mbps (max). The series of digital isolators conforms to the AEC-Q100 standard on the safety and reliability of automotive electronic components.

The isolators feature Toshiba’s proprietary magnetic coupling type isolated transmission method to achieve a high CMTI of 100 kV/μs (typ.). This delivers high-level resistance to electric 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 0.8 ns (typ.) and a data-transmission rate of 50 Mbps are also achieved. The new products are suitable for multi-channel high-speed communication applications such as I/O interfaces with SPI communications.
