Features
Description
In order to prevent fast transients from leading to
severe damages in a high speed data system, a
specific protection has been developed by
STMicroelectronics.
The USB6B1 protects the two input lines against
overvoltage. Besides, this device also keeps the
power rails in a safe limit thanks to the integrated
Transil diode.
