Digital Isolators Resist Electrical Noise
Toshiba Electronic Devices & Storage Corporation announced October 27 it had launched four digital isolaters for use in industrial environments. According to a company release, the four chips in the DCL52XX00 series support stable operation at 150Mbps.
There are four chips in the series: DCL5200C00 and DCL520D00 both have two forward channels, while the DCL521C00 and DCL521D00 each have one forward and one reverse channel. All four isolaters to protect input and output signal transmissions from electrical noise interference, with a high Common Mode Transient Immunity (CMTI) of 100kV/μs.
Toshiba also says the isolaters have a low pulse width distortion of 0.8ns and are suitable for multi-channel high-speed communication applications, including I/O interfaces with UART and I2C communication.
The isolators are for application in industrial automation systems, motor control units, or inverters, and can be operated at -40 to 125 degrees Centigrade (-40 to 257 degrees Fahrenheit).
