20.5 RS232 Interface Discrete ESD Protection Solution
The RS-232 standard interface, also known as EIA RS-232, is a commonly used serial communication interface standard, typically applied in short-distance point-to-point communication. This interface is used on communication devices as a test interface, board-to-board communication interface, and monitoring signal interface, with a maximum baud rate of 115,200 bps. Solution Advantages: This solution adopts discrete devices for protection, ensuring signal integrity while passing ESD testing. Compliance: Meets IEC61000-4-2, ISO10605-2, Class 4, withstanding contact discharge of 30kV and air discharge of 30kV.
