20.1 RS232 Interface Integrated Electrostatic Protection Solution
The RS-232 standard interface, also known as EIA RS-232, is a commonly used serial communication interface standard, typically applied to point-to-point communication over shorter distances. This interface is often used as a test interface on communication devices, and as a communication interface between boards and monitoring signal interfaces, with a maximum baud rate of 115,200 bps. Solution Advantages: This solution employs integrated components for protection, ensuring signal integrity while passing electrostatic discharge (ESD) tests. It complies with IEC61000-4-2, ISO10605-2, Level 4 standards, and supports contact discharge of 30kV and air discharge of 30kV.
