Toshiba DCL52xx00 Series standard digital isolators

Toshiba has launched four dual-channel, high-speed standard digital isolators for industrial equipment. The DCL52xx00 Series products support stable operation with high common mode transient immunity (CMTI) of 100 kV/μs (typ) and high-speed data rate of 150 Mbps (max).

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 the DCL54xx01 Series as standard digital isolators for industrial equipment.

The DCL52xx00 Series products use Toshiba’s proprietary magnetic coupling type isolated transmission method to achieve a high CMTI of 100 kV/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 0.8 ns (typ) and a high-speed data rate of 150 Mbps (max) are also achieved. The new products are suitable for multi-channel high-speed communication applications such as I/O interfaces with UART and I2C communication.

Toshiba has 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 also continue to provide isolation devices and photocouplers that support the reliability and real-time data transmission required by industrial and automotive equipment.
